The standard sets particular safety requirements tailored to refrigerant recovery/recycle appliances and covers a broad set of technical topics, including:
- Scope and definitions specific to recovery/recycle appliances (Clause 1–3)
- Marking and instructions: mandatory markings, symbols (e.g., “read operator’s manual”) and maximum allowable pressure markings (Clause 7)
- Electrical safety: protection against access to live parts, leakage current, electric strength, transient overvoltages, and motor starting (Clauses 8–15)
- Temperature and heating limits: winding and abnormal temperature limits and related test methods (Tables and Annex AA)
- Mechanical construction and strength: stability, mechanical hazards, internal wiring, components, terminals and earthing (Clauses 20–28)
- Pressure and leak integrity: pressure strength tests, pressure values and leak simulation tests (Annexes CC, DD and relevant clauses)
- Compatibility and refrigerant considerations: compatibility testing for refrigerants and refrigerant-containing parts (Annex BB)
- Fire, corrosion and toxic hazards: resistance to heat, fire, rusting and radiation/toxicity checks (Clauses 30–32)

Part 2-104: Particular requirements for appliances to recover and/or
recycle refrigerant from air conditioning and refrigeration equipment
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal
use taking into account the manufacturer's instructions. It also covers abnormal situations that
can be expected in practice and takes into account the way in which electromagnetic
phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that there
is compatibility with the wiring rules when the appliance is connected to the supply mains.
However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of the
requirements and, if found to be substantially equivalent, may be considered to comply with the
standard.

10 Power input and current
This clause of Part 1 is applicable.
11 Heating
This clause of Part 1 is replaced by the following.
11.1 Appliances and their surroundings shall not attain excessive temperatures in normal use.
Compliance is checked by determining the temperatures of the various parts under the
conditions specified in 11.2 to 11.7. Nevertheless, if the temperature of the motor winding
exceeds the value specified in Table 1 or if there is a doubt with regard to the classification of
the insulation system employed in a motor, compliance is checked by the tests of Annex C.
11.2 The appliance is installed in a test room in accordance with the manufacturer’s
installation instructions. In particular
– clearances to adjacent surfaces specified by the manufacturer shall be maintained;
– adjustable limit controls are set at the maximum cut-out setting and the minimum differential
permitted by the control adjusting means.
11.3 Temperatures are determined by means of fine-wire thermocouples so chosen and
positioned that they have the minimum effect on the temperature of the part under test.
NOTE 101 Thermocouples having wires with a diameter not exceeding 0,3 mm are considered to be fine-wire
thermocouples.
The temperature of motor windings or of coils may be measured by the change-in-resistance
method.
Thermocouples used for determining the temperatures of the surface of walls, ceiling and floor
are embedded in the surface or attached to the back of small blackened disks of copper or
brass, 15 mm in diameter and 1 mm thick, which are flush with the surface.
So far as is possible, the appliance is positioned so that parts likely to attain the highest
temperatures touch the disks.
In determining the temperatures of handles, knobs, grips and the like, consideration is given to
all parts which are gripped in normal use and, if of insulating material, to parts in contact with
hot metal.
The temperature of electrical insulation, other than that of windings, is determined on the
surface of the insulation, at places where failure could cause a short circuit, contact between
live parts and accessible metal parts, bridging of insulation or reduction of creepage distances
or clearances below the values specified in 29.1.
11.4 Appliance is operated at normal operating voltage in a test room maintained at 43 °C or
at the maximum temperature specified by the manufacturer if higher, until temperatures reach
stabilisation.

capabilities as determined by aging tests made on the materials themselves.
NOTE 101 The value of the temperature of a winding is calculated from the formula:
R
T = (k+ T )− k
R
where
T is the temperature of the copper winding at the end of the test;
R is the resistance at the beginning of the test;
R is the resistance at the end of the test;
T is the ambient temperature at the beginning of the test;
k is equal to 234,5 for copper windings and 225 for aluminium windings.
At the beginning of the test, the windings are at ambient temperature.
the resistance of windings at the end of the test is determined by taking resistance measurements as soon as possible
after switching off, and then at short intervals so that a curve of resistance against time can be plotted for
ascerTaining the resistance at the instant of switching off.

may be present in the appliance.
Compliance is checked by the tests of 15.2, followed immediately by the spillage test of 15.3,
and this is followed by the tests of 11.6 and the tests of Clause 16.
Following these tests, an inspection is made within the enclosures. The water which may have
entered the enclosure shall not have reduced the creepage distances and clearances below the
minimum values specified in Clause 29.
NOTE 101 Appliances designed to be installed completely inside a building and which have no outdoor parts are
not subjected to the test of 15.2.
The motor-compressor is not operated during the tests of 15.2 and 15.3.
15.2 Appliances other than IPXO are subjected to the tests of IEC 60529:1989 as follows:

Part 2-104: Particular requirements for appliances to recover and/or
recycle refrigerant from air conditioning and refrigeration equipment
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal
use taking into account the manufacturer's instructions. It also covers abnormal situations that
can be expected in practice and takes into account the way in which electromagnetic
phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that there
is compatibility with the wiring rules when the appliance is connected to the supply mains.
However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of the
requirements and, if found to be substantially equivalent, may be considered to comply with the
standard.

SAFETY –
Part 2-104: Particular requirements for appliances to recover and/or
recycle refrigerant from air conditioning and refrigeration equipment
1 Scope
This clause of Part 1 is replaced by the following:
This part of IEC 60335 deals with the safety of electrical appliances recovery and/or recycle
equipment to recover and/or recycle refrigerant from air conditioning and refrigeration
equipment. This applies to air-conditioning, heat-pumps and refrigeration equipment
incorporating open drive or motor-compressors, their maximum rated voltages being not more
than 250 300 V for single phase appliances and 600 V for all other appliances equipment.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used by service personnel in shops, in
light industry and on farms, are within the scope of this standard.
The appliances referenced above may consist of one or more factory made assemblies. If
provided in more than one assembly, the separate assemblies are to be used together, and the
requirements are based on the use of matched assemblies.
NOTE 101 A definition of “sealed motor-compressor” is given in IEC 60335-2-34.
NOTE 102 Requirements for refrigeration safety are covered by ISO 5149.
NOTE 103 For appliances using flammable refrigerants, additional requirements are under consideration.
NOTE 104 Attention is drawn to the fact that
− for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
− for appliances subjected to pressure, additional requirements may be necessary;
− in many countries additional requirements are specified by the national health authorities, the national authorities
responsible for the protection of labour, national water supply authorities and similar authorities.
NOTE 105 This standard does not apply to
− appliances designed exclusively for industrial processing;
− appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive
or explosive atmosphere (dust, vapour or gas).

This clause of Part 1 is replaced by the following.
11.1 Appliances and their surroundings shall not attain excessive temperatures in normal use.
Compliance is checked by determining the temperatures of the various parts under the
conditions specified in 11.2 to 11.7. Nevertheless, if the temperature of the motor winding
exceeds the value specified in Table 3 Table 1 or if there is a doubt with regard to the
classification of the insulation system employed in a motor, compliance is checked by the tests
of Annex C.
11.2 The appliance is installed in a test room in accordance with the manufacturer’s
installation instructions. In particular
– clearances to adjacent surfaces specified by the manufacturer shall be maintained;
– adjustable limit controls are set at the maximum cut-out setting and the minimum differential
permitted by the control adjusting means.
11.3 Temperatures are determined by means of fine-wire thermocouples so chosen and
positioned that they have the minimum effect on the temperature of the part under test.
NOTE 101 Thermocouples having wires with a diameter not exceeding 0,3 mm are considered to be fine-wire
thermocouples.
The temperature of motor windings or of coils may be measured by the change-in-resistance
method.
Thermocouples used for determining the temperatures of the surface of walls, ceiling and floor
are embedded in the surface or attached to the back of small blackened disks of copper or
brass, 15 mm in diameter and 1 mm thick, which are flush with the surface.
So far as is possible, the appliance is positioned so that parts likely to attain the highest
temperatures touch the disks.
In determining the temperatures of handles, knobs, grips and the like, consideration is given to
all parts which are gripped in normal use and, if of insulating material, to parts in contact with
hot metal.
The temperature of electrical insulation, other than that of windings, is determined on the
surface of the insulation, at places where failure could cause a short circuit, contact between
live parts and accessible metal parts, bridging of insulation or reduction of creepage distances
or clearances below the values specified in 29.1.
11.4 Appliance is operated at normal operating voltage in a test room maintained at 43 °C or

AVANT-PROPOS
1) La Commission Électrotechnique Internationale (IEC) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l'IEC). L'IEC a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. À cet effet, l'IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l'IEC"). Leur élaboration est confiée à des comités d'études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l'IEC, participent également aux
travaux. L'IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l'IEC concernant les questions techniques représentent, dans la mesure du
possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l'IEC intéressés
sont représentés dans chaque comité d'études.
3) Les Publications de l'IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l'IEC. Tous les efforts raisonnables sont entrepris afin que l'IEC
s'assure de l'exactitude du contenu technique de ses publications; l'IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l'IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l'IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l'IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L'IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l'IEC. L'IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l'IEC, à ses administrateurs, employés, auxiliaires ou mandataires,
y compris ses experts particuliers et les membres de ses comités d'études et des Comités nationaux de l'IEC,
pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre dommage de quelque
nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais de justice) et les dépenses
découlant de la publication ou de l'utilisation de cette Publication de l'IEC ou de toute autre Publication de l'IEC,
ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L'attention est attirée sur le fait que certains des éléments de la présente Publication de l'IEC peuvent faire l'objet
de droits de brevet. L'IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits de
brevets.

INTRODUCTION
Il a été admis en établissant la présente Norme internationale que l'exécution de ses
dispositions était confiée à des personnes expérimentées et ayant une qualification appropriée.
La présente norme reconnaît le niveau de protection internationalement accepté contre les
dangers électriques, mécaniques, thermiques, liés au feu et au rayonnement des appareils,
lorsqu'ils fonctionnent comme en usage normal en tenant compte des instructions du fabricant.
Elle couvre également les situations anormales auxquelles on peut s'attendre dans la pratique
et elle tient compte de la façon dont les phénomènes électromagnétiques peuvent altérer le
fonctionnement sûr des appareils.
La présente norme tient compte autant que possible des exigences de l'IEC 60364, de façon à
rester compatible avec les règles d'installation quand l'appareil est raccordé au réseau
d'alimentation. Cependant, des règles nationales d'installation peuvent être différentes.
Si un appareil relevant du domaine d'application de la présente norme comporte également des
fonctions couvertes par une autre partie 2 de l'IEC 60335, la partie 2 correspondante est
appliquée à chaque fonction séparément, dans la limite du raisonnable. Si cela est applicable,
l'influence d'une fonction sur les autres fonctions est prise en compte.
Lorsqu'une partie 2 ne comporte pas d'exigences complémentaires pour couvrir les dangers
traités dans la Partie 1, la Partie 1 s'applique.
NOTE 1 Cela signifie que les comités d'études responsables pour les parties 2 ont déterminé qu'il n'était pas
nécessaire de spécifier des exigences particulières pour l'appareil en question en plus des exigences générales.
La présente norme est une norme de famille de produits traitant de la sécurité d'appareils et a
préséance sur les normes horizontales et génériques couvrant le même sujet.
NOTE 2 Les normes horizontales et génériques couvrant un risque ne sont pas applicables parce qu'elles ont été
prises en considération lorsque les exigences générales et particulières ont été étudiées pour la série de normes
IEC 60335. Par exemple, dans le cas des exigences de température de surface pour de nombreux appareils, des
normes génériques, comme l'ISO 13732-1 pour les surfaces chaudes, ne sont pas applicables en plus de la Partie 1
ou des parties 2.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé conforme
aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux essais, il apparaît
qu'il présente d'autres caractéristiques qui compromettent le niveau de sécurité visé par ces
exigences.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de ceux
décrits dans les exigences de la présente norme peut être examiné et soumis aux essais en
fonction de l'objectif poursuivi par ces exigences et, s'il est jugé pratiquement équivalent, il peut
être estimé conforme aux principes de sécurité de la norme.
1 Domaine d'application
L'article de la Partie 1 est remplacé par le texte suivant:
La présente partie de l'IEC 60335 traite de la sécurité des appareils électriques de
récupération et/ou de recyclage des fluides frigorigènes des climatiseurs et des appareils
de réfrigération. Elle s'applique aux climatiseurs, pompes à chaleur et appareils de réfrigération
qui comportent des compresseurs à circuit ouvert ou des motocompresseurs, dont la tension
maximale assignée n'est pas supérieure à 300 V pour les appareils monophasés et à 600 V
pour les autres appareils.
Les appareils non destinés à un usage domestique normal, mais qui peuvent néanmoins
constituer une source de danger pour le public, tels que les appareils destinés à être utilisés
par le personnel de service dans des magasins, chez des artisans et dans des fermes, relèvent
du domaine d'application de la présente norme.
Les appareils indiqués ci-dessus peuvent consister en une ou plusieurs parties assemblées en
usine. S'ils sont livrés en plus d'une partie, les différentes parties doivent être utilisées
ensemble et les exigences sont fondées sur l'utilisation de ces parties assemblées.
NOTE 101 Dans le présent document, le terme "appareil" est utilisé pour désigner les appareils de récupération.

8 Protection contre l'accès aux parties actives
L'article de la Partie 1 s'applique.
9 Démarrage des appareils à moteur
L'article de la Partie 1 ne s'applique pas.
10 Puissance et courant
L'article de la Partie 1 s'applique.
11 Échauffements
L'article de la Partie 1 est remplacé par le texte suivant.
11.1 Les appareils et leurs environnements ne doivent pas atteindre une température
excessive en usage normal.
La vérification est effectuée en déterminant les températures des différentes parties dans les
conditions spécifiées du 11.2 au 11.7. Néanmoins, si la température d'un enroulement de
moteur dépasse la valeur spécifiée dans le Tableau 1 ou s'il y a doute en ce qui concerne la
classification du système d'isolation employé dans un moteur, la vérification est effectuée par
les essais de l'Annexe C.
11.2 L'appareil est installé dans le local d'essai suivant les instructions d'installation du
fabricant. En particulier:
– les distances dans l'air des surfaces adjacentes spécifiées par le fabricant doivent être
respectées;
– les dispositifs limiteurs réglables sont réglés à leur valeur maximale de coupure et au
différentiel minimal admis par leurs dispositifs de réglage.
11.3 Les températures sont déterminées au moyen de thermocouples à fil fin choisis et placés
de façon à avoir l'influence la plus faible sur la température de la partie en essai.
NOTE 101 Les thermocouples ayant des fils d'un diamètre ne dépassant pas 0,3 mm sont considérés comme des
thermocouples à fil fin.
La température des enroulements de moteurs ou des bobines peut être mesurée par la méthode
de la variation de résistance.
Les thermocouples utilisés pour déterminer la température des surfaces des murs, planchers
et plafonds sont encastrés dans la surface ou fixés au dos de petits disques de cuivre ou de
laiton noircis de 15 mm de diamètre et 1 mm d'épaisseur placés au ras de la surface.
Dans la mesure du possible, l'appareil est placé de façon que les parties susceptibles
d'atteindre les plus hautes températures touchent les disques.
Pour la détermination des températures des poignées, boutons, manettes et organes
analogues, il est tenu compte de toutes les parties qui sont saisies en usage normal et, si elles
sont en matériau isolant, des parties en contact avec le métal chaud.
La température de l'isolation électrique, autre que celle des enroulements, est déterminée sur
la surface de l'isolant, aux endroits où un défaut pourrait produire un court-circuit, un contact
entre des parties actives et des parties métalliques accessibles, un pontage de l'isolation ou
une réduction des lignes de fuite ou des distances dans l'air au-dessous des valeurs
spécifiées au 29.1.
11.4 L'appareil est mis en fonctionnement à une tension de fonctionnement normale dans une
salle d'essai dont la température est maintenue à 43 °C ou à la température maximale spécifiée
par le fabricant si elle est supérieure, jusqu'à ce que les températures se stabilisent.
11.5 Les appareils du type à refroidissement à eau doivent être mis en fonctionnement, le
débit de l'eau étant maintenu à la condition la plus sévère spécifiée par le fabricant.
11.6 Tous les appareils sont mis en fonctionnement en continu jusqu'à obtention des
conditions continues. Tous les appareils doivent fonctionner conformément aux conditions de
l'Annexe AA.
11.7 Pendant l'essai, les températures et les pressions sont relevées en permanence et ne
doivent pas dépasser celles données dans le Tableau 1. Les dispositifs de protection ne
doivent pas fonctionner et la matière de remplissage ne doit pas couler. Les pressions sont
enregistrées et utilisées à l'Article 21.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 60335-2-104 has been prepared by subcommittee 61D: Appliances for air-conditioning for
household and similar purposes, of IEC technical committee 61: Safety of household and similar
electrical appliances. It is an International Standard.
This second edition cancels and replaces the first edition published in 2003. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous

The text of this International Standard is based on the following documents:
Draft Report on voting
61D/472/FDIS 61D/474/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/publications.
A list of all parts of the IEC 60335 series, under the general title Household and similar electrical
appliances – Safety, can be found on the IEC website.
This part 2 is to be used in conjunction with the fifth edition of IEC 60335-1:2010 and its
amendments.
NOTE 1 When "Part 1" is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1 so as to convert
that publication into the IEC Standard: Safety requirements for electrical appliances to recover
and/or recycle refrigerant from air conditioning and refrigeration equipment.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as
far as is reasonable. When this standard states "addition", "modification" or "replacement", the
relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those
in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting
from 101, including those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 3 The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in smaller roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally
not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries indicated below:
• 6.1: Class 01 appliances are allowed (Japan).
• 11.8: The temperature of the wooden walls in the test casing is limited to 85 °C (Sweden).
INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal
use taking into account the manufacturer's instructions. It also covers abnormal situations that
can be expected in practice and takes into account the way in which electromagnetic
phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that there
is compatibility with the wiring rules when the appliance is connected to the supply mains.
However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of the
requirements and, if found to be substantially equivalent, may be considered to comply with the
standard.
1 Scope
This clause of Part 1 is replaced by the following:
This part of IEC 60335 deals with the safety of electrical recovery and/or recycle equipment
to recover and/or recycle refrigerant from air conditioning and refrigeration equipment. This
applies to air-conditioning, heat-pumps and refrigeration equipment incorporating open drive or
motor-compressors, their maximum rated voltages being not more than 300 V for single phase
appliances and 600 V for all other equipment.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used by service personnel in shops, in
light industry and on farms, are within the scope of this standard.
The appliances referenced above may consist of one or more factory made assemblies. If
provided in more than one assembly, the separate assemblies are to be used together, and the
requirements are based on the use of matched assemblies.
NOTE 101 In this document, the term appliance is to denote recovery equipment.

8 Protection against access to live parts
This clause of Part 1 is applicable.
9 Starting of motor-operated appliances
This clause of Part 1 is not applicable.
10 Power input and current
This clause of Part 1 is applicable.
11 Heating
This clause of Part 1 is replaced by the following.
11.1 Appliances and their surroundings shall not attain excessive temperatures in normal use.
Compliance is checked by determining the temperatures of the various parts under the
conditions specified in 11.2 to 11.7. Nevertheless, if the temperature of the motor winding
exceeds the value specified in Table 1 or if there is a doubt with regard to the classification of
the insulation system employed in a motor, compliance is checked by the tests of Annex C.
11.2 The appliance is installed in a test room in accordance with the manufacturer’s
installation instructions. In particular
– clearances to adjacent surfaces specified by the manufacturer shall be maintained;
– adjustable limit controls are set at the maximum cut-out setting and the minimum differential
permitted by the control adjusting means.
11.3 Temperatures are determined by means of fine-wire thermocouples so chosen and
positioned that they have the minimum effect on the temperature of the part under test.
NOTE 101 Thermocouples having wires with a diameter not exceeding 0,3 mm are considered to be fine-wire
thermocouples.
The temperature of motor windings or of coils may be measured by the change-in-resistance
method.
Thermocouples used for determining the temperatures of the surface of walls, ceiling and floor
are embedded in the surface or attached to the back of small blackened disks of copper or
brass, 15 mm in diameter and 1 mm thick, which are flush with the surface.
So far as is possible, the appliance is positioned so that parts likely to attain the highest
temperatures touch the disks.
In determining the temperatures of handles, knobs, grips and the like, consideration is given to
all parts which are gripped in normal use and, if of insulating material, to parts in contact with
hot metal.
The temperature of electrical insulation, other than that of windings, is determined on the
surface of the insulation, at places where failure could cause a short circuit, contact between
live parts and accessible metal parts, bridging of insulation or reduction of creepage distances
or clearances below the values specified in 29.1.
11.4 Appliance is operated at normal operating voltage in a test room maintained at 43 °C or
at the maximum temperature specified by the manufacturer if higher, until temperatures reach
stabilisation.
11.5 Appliances of the water-cooled type shall be operated with the water flow maintained at
the most severe condition as specified by the manufacturer.
11.6 All appliances are operated continuously until steady state conditions are obtained. All
appliances shall be operated according to the conditions in Annex AA.
11.7 During the test, the temperatures and pressures are monitored continuously and shall
not exceed the values shown in Table 1. Protective devices shall not operate and sealing
compound shall not flow out. Pressures are recorded and used in Clause 21.

h
There is no limit for the temperature rise of capacitors which are short-circuited in 19.7.
i
Temperature marking for capacitors mounted on printed circuit boards may be given in the technical sheet.
If these or other materials are used, they shall not be subjected to temperatures in excess of the thermal
capabilities as determined by aging tests made on the materials themselves.
NOTE 101 The value of the temperature of a winding is calculated from the formula:
R
T = (k+ T )− k
R
where
T is the temperature of the copper winding at the end of the test;
R is the resistance at the beginning of the test;
R is the resistance at the end of the test;
T is the ambient temperature at the beginning of the test;
k is equal to 234,5 for copper windings and 225 for aluminium windings.
At the beginning of the test, the windings are at ambient temperature.
the resistance of windings at the end of the test is determined by taking resistance measurements as soon as possible
after switching off, and then at short intervals so that a curve of resistance against time can be plotted for ascertaining
the resistance at the instant of switching off.
