AVANT-PROPOS
1) La CEI (Commission Electrotechnique Internationale) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. A cet effet, la CEI, entre autres activités, publie des Normes internationales.
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 la CEI, participent également aux travaux. La CEI 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 la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux intéressés
sont représentés dans chaque comité d’études.
3) Les documents produits se présentent sous la forme de recommandations internationales. Ils sont publiés
comme normes, spécifications techniques, rapports techniques ou guides et agréés comme tels par les Comités
nationaux.
4) Dans le but d'encourager l'unification internationale, les Comités nationaux de la CEI s'engagent à appliquer de
façon transparente, dans toute la mesure possible, les Normes internationales de la CEI dans leurs normes
nationales et régionales. Toute divergence entre la norme de la CEI et la norme nationale ou régionale
correspondante doit être indiquée en termes clairs dans cette dernière.
5) La CEI n’a fixé aucune procédure concernant le marquage comme indication d’approbation et sa responsabilité
n’est pas engagée quand un matériel est déclaré conforme à l’une de ses normes.
6) L’attention est attirée sur le fait que certains des éléments de la présente Norme internationale peuvent faire
l’objet de droits de propriété intellectuelle ou de droits analogues. La CEI ne saurait être tenue pour
responsable de ne pas avoir identifié de tels droits de propriété et de ne pas avoir signalé leur existence.
La Norme internationale CEI 60730-2-17 a été établie par le comité d'études 72 de la CEI:
Commandes automatiques pour appareils domestiques.
La présente version consolidée de la CEI 60730-2-17 comprend la première édition (1997)
[documents 72/348/FDIS et 72/371/RVD] et son amendement 1 (2000) [documents
72/466/FDIS et 72/490/RVD].
Le contenu technique de cette version consolidée est donc identique à celui de l'édition de

base et à son amendement; cette version a été préparée par commodité pour l'utilisateur.
Elle porte le numéro d'édition 1.1.
Une ligne verticale dans la marge indique où la publication de base a été modifiée par les
amendement 1.
La présente partie 2 doit être utilisée conjointement avec la CEI 60730-1. Elle a été établie sur
la base de la troisième édition (1999) de cette publication. Les éditions ou amendements futurs
de la CEI 60730-1 pourront être pris en compte.

AUTOMATIC ELECTRICAL CONTROLS
FOR HOUSEHOLD AND SIMILAR USE –

Part 2-17: Particular requirements for electrically operated gas valves,

including mechanical requirements

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60730-2-17 has been prepared by IEC technical committee 72:
Automatic controls for household use.
This consolidated version of IEC 60730-2-17 consists of the first edition (1997) [documents
72/348/FDIS and 72/371/RVD], and its amendment 1 (2000) [documents 72/466/FDIS and
72/490/RVD].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.

It bears the edition number 1.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
This part 2 is intended to be used with IEC 60730-1. It was established on the basis of the third
edition (1999) of that publication. Consideration may be given to future editions of, or
amendments to IEC 60730-1.
Where this part 2 states "addition", "modification" or "replacement", the relevant requirement,
test specification or explanatory matter in part 1 should be adapted accordingly.

Part 2-17: Particular requirements for electrically operated gas valves,
including mechanical requirements

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.
International Standard IEC 60730-2-17 has been prepared by IEC technical committee 72:
Automatic controls for household use.
This consolidated version of IEC 60730-2-17 consists of the first edition (1997) [documents
72/348/FDIS and 72/371/RVD], its amendment 1 (2000) [documents 72/466/FDIS and
72/490/RVD] and its amendment 2 (2007) [documents 72/744/FDIS and 72/749/RVD].
The technical content is therefore identical to the base edition and its amendments and has
been prepared for user convenience.
It bears the edition number 1.2.
A vertical line in the margin shows where the base publication has been modified by
amendments 1 and 2.
– 4 – 60730-2-17 © IEC:1997+A1:2000
+A2:2007
This Part 2-17 is intended to be used in conjunction with IEC 60730-1. It was established on
the basis of the third edition of that standard (1999) and its amendment 1 (2003).
Consideration may be given to future editions of, or amendments to IEC 60730-1.
Where this part 2 states "addition", "modification" or "replacement", the relevant requirement,
test specification or explanatory matter in part 1 should be adapted accordingly.
Where no change is necessary, part 2 indicates that the relevant clause or subclause applies.
In the development of a fully international standard it has been necessary to take into
consideration the differing requirements resulting from practical experience in various parts of
the world and to recognize the variation in national electrical systems and wiring rules.
The “in some countries” notes regarding differing national practice are contained in the following subclauses:
– 6.11.101
– 6.103
– 6.104
– Table 7.2, requirements 117 and 118
– Table 7.2, notes 103 and 104

– 11.115
– 17.16.101
– 18.102
– 18.103
– 27.2.101.1
In this publication:
1) The following print types are used:
–  Requirements proper: in roman type;
– Test specifications: in italic type;
– Explanatory matter: in smaller roman type.
2) Subclauses, notes or requirements which are additional to those in part 1 are numbered
starting from 101.
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the maintenance result date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date,
the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

AUTOMATIC ELECTRICAL CONTROLS
FOR HOUSEHOLD AND SIMILAR USE –

Part 2-17: Particular requirements for electrically operated gas valves,
including mechanical requirements

1 Scope and normative references
This clause of part 1 is replaced as follows:
Replacement:
1.1 This part 2 of IEC 60730 applies to electrically operated gas valves for use in, on or in
association with, equipment for household and similar use that use electricity, in combination
with fuel in the gaseous state such as manufactured gas, natural gas or liquefied petroleum
gas intended to be used for gas burning equipment.
Additional considerations may be necessary for gas with corrosive properties.
This part 2 also applies to electrically operated gas valves using NTC or PTC thermistors,
requirements for which are contained in annex J.
1.1.1 This standard applies to the inherent safety, to the operating values, operating times,
and operating sequences where such are associated with equipment safety, and to the testing
of electrically operated gas valves used in, or in association with, household or similar
equipment, but also extended to industrial purposes when no dedicated product standard
exists, such as that for central heating, air conditioning, process heating, etc.
This part 2 is also applicable to controls for appliances within the scope of IEC 60335-1.
Throughout this part 2 the word "equipment" means "appliance and equipment".
This part 2 does not apply to electrically operated gas valves designed exclusively for industrial
applications.
Electrically operated gas valves for equipment not intended for normal household use, but
which nevertheless may be used by the public, such as equipment intended to be used by
laymen in shops, in light industry and on farms, are within the scope of this part 2.
This part 2 identifies a number of mechanical features as "under consideration". Until these
mechanical requirements are incorporated in this part 2, each country using this part 2 will
have to quantify these requirements.
Compliance of an electrically operated gas valve with this part 2 does not imply that the valve is acceptable without
further tests for these mechanical features.
1.1.2 This part 2 applies to manual controls when such are electrically and/or mechanically
integral with electrically operated gas valves.
Requirements for manual switches not forming part of an electrically operated gas valve are contained in
IEC 61058-1.
– 6 – 60730-2-17 © IEC:1997+A1:2000
+A2:2007
This part 2 does not apply to electrically operated gas valves of nominal connection size above
DN 150.
This part 2 applies to electrically operated gas valves for maximum working pressures up
to 400 kPa (4 bar).
Hereinafter, the term "valve" is used to denote an electrically operated gas valve (including
prime mover and valve body).
1.1.3  An electric actuator that is submitted to the testing laboratory in combination with a gas
valve will be evaluated under this part 2. A separate electric actuator is evaluated under
IEC 60730-2-14, which provides particular requirements for electric actuators.
1.1.4 This part 2 also applies to valves utilized as part of a system, or valves mechanically
integral with multifunctional controls.
1.1.5 This part 2 does not apply to valves energized by thermoelectric energy generated in a
thermocouple or thermopile inserted in a gas flame.
1.3 Is not applicable.

60730-2-17 © IEC:1997+A1:2000 – 15 –
+A2:2007
11.3.4 Setting by the manufacturer
Replacement:
Adjustment means shall be secured by means providing protection against access by
uninstructed persons or shall be declared as requiring such protection in the application.
For example, these means may:
a) be sealed with a material suitable for the temperature range of the valve such that tampering is apparent; or
b) be accessible only with the use of special purpose tools; or
c) be accompanied by instructions requiring the equipment manufacturer to mount the valve such that the
adjustment means is inaccessible.
Compliance is checked by inspection. Where sealing is used, inspection is done before and
after the tests of clause 17.
Additional subclauses:
11.3.4.101  Suitable means for maintaining all adjustments shall be provided.
Lock nuts or adjusting nuts held by springs or compression are acceptable unless their adjustment can be
accidentally disturbed.
11.3.4.102  Necessary field adjustments shall be capped or otherwise protected in such a
manner as to resist tampering or accidental change.
11.3.4.103  If a valve can be partially or completely disassembled without the use of special
tools, construction shall be such that either:
a) parts of the valve cannot be readily reassembled improperly in a manner which could result
in an unsafe condition, or
b) threaded fasteners are covered with a sealing means to discourage disassembly. The
sealing means shall be suitable for exposure to the minimum and maximum ambient
temperatures declared for the valve.
This subclause does not apply to parts of a valve intended for field replacement or servicing (as declared in table
7.2, requirement 108).
11.3.9 Pull-cord actuated control
Replacement:
11.3.9.101  Operation of a manually actuated mechanism of a valve shall not subject parts to
distortion or damage to the extent that their intended function is impaired.
Compliance is checked by operation and inspection.
11.3.9.102  Operating parts shall be separated from conductors to be connected to the valve
by barriers or by their physical location so that such operating parts are not obstructed by these
conductors.
Compliance is checked by operation and inspection.

11.102 For valves intended for exposure to the outdoor environment, the protection of the
electrical parts by the enclosure shall conform to at least IP54 unless that protection is afforded
by the equipment.
In the countries members of CENELEC, the ambient temperature range of these valves shall be at least –20 °C to
+60 °C.
Compliance is checked by inspection and the tests of IEC 60529, after pre-conditioning of a
sample as indicated in clause 12.
11.103 Normally closed (normally open) valves shall be constructed to assume the de-
energized position at reduced supply voltage.
Compliance is checked by connecting the normally closed (normally open) valve to the supply
at rated voltage, at room temperature and when mounted in the most unfavourable position
declared in Table 7.2, requirement 31, and with or without air at the maximum working pressure
connected to the valve inlet, whichever is more unfavourable. The voltage is then slowly
reduced to 15 % of the minimum rated voltage. Before this value is reached, the valve shall
have closed (opened) automatically.
The test is repeated three times.
In the USA and Canada, for d.c. valves, the voltage is slowly reduced to 2 % of the minimum rated voltage.
The value of 15% is based on the usual normally closed valves where remanence, friction and possible rest
currents due to control and signalling circuits can influence the closing force.
11.104 Miscellaneous construction requirements
11.104.1 For normally closed, normally open and safety shutoff valves of the automatic type,
there shall be no exposed shafts or operating levers where interference could affect the ability
of the valve to close.
11.104.2 Holes for screws, pins, etc., which are used for the assembly of parts or used to
install the valve shall not penetrate gasways.
11.104.3 Parts of the valve housing that directly or indirectly separate a gas-carrying
compartment from the atmosphere shall be manufactured only of metallic materials with a
melting point of not less than 450 °C.
Soldering or other processes where the jointing material has a melting point below 450 °C after
application shall not be used for joining gas-carrying parts.
A gas-carrying compartment may be made of non-metallic material provided that upon removal
or fracture of this non-metallic part, not more than 30 dm /h of air can escape to atmosphere at
maximum working pressure.
This subclause is not intended to cover o-rings, gaskets, seals, or diaphragms.
In the countries members of CENELEC, ZnAl according to ISO 301 is allowed in certain valve configurations.
11.104.4 Holes necessary in manufacture which connect gasways to the atmosphere but
which do not affect the function of the valve shall be permanently sealed by metallic means.
Suitable jointing compounds may additionally be used.

+A2:2007
11.104.5 The valve shall be constructed such that leak-tightness in accordance with 11.108
will be achieved by mechanical means (for example, metal to metal joints, o-rings). If the
manufacturer specifies servicing or maintenance which requires access or disassembly,
leak-tightness shall also be maintained after the specified disassembly and reassembly.
In the countries members of CENELEC, the leakage test shall be carried out after five times disassembly and
reassembly.
11.104.6 Self-tapping screws that cut a thread and produce swarf shall not be used for
connecting gas-carrying parts or parts that must be removed for specified servicing.
11.104.7 Springs shall be protected against abrasion and guided or arranged to minimize
binding, buckling, or other interference with their free movement.
Springs providing the closing forces or opening forces in the case of normally open valves shall
be designed for oscillating loads and for fatigue resistance. These springs shall be either made
from corrosion resistant material or suitably protected against corrosion.
11.104.8 Any part in contact with gas shall be manufactured from corrosion resistant
materials or suitably protected against corrosion and shall be resistant to the effects of gas.
11.104.9 For pneumatically or hydraulically actuated valves, where the blockage of an orifice
can adversely affect the closing or opening in the case of normally open valves, protection to
avoid any such blockage shall be provided.
11.104.10 Diaphragm type valves in which a flexible non-metallic diaphragm constitutes the
only gas seal and which utilize control gas on one side of the diaphragm shall have that side of
the diaphragm enclosed in gas-tight housing with means provided for bleeding the control gas.
11.104.11 Valves, in which a flexible non-metallic diaphragm constitutes the only gas seal,
shall have the atmospheric side of the diaphragm enclosed to limit the leakage to atmosphere
in the event of diaphragm rupture to not more than 70 dm /h at the maximum working pressure
of the valve when tested with air, or shall be provided with means for venting the gas in the
event of diaphragm rupture.
3 3
In the USA and Canada, for liquid petroleum gases the value is 30 dm /h and 70 dm /h for natural gas.
11.104.12 Parts of valves coming in contact with a diaphragm shall not have sharp edges
which might chafe or abrade it.
11.104.13 A valve shall be designed to accept a spanner for assembly and disassembly to
piping or tubing.
11.104.14 When a pressure test gauge connection is provided as part of the valve, this
connection shall be:
