Part 2-118: Particular requirements for professional ice-cream makers

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. 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.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 and SC 61C supporting documents on the IEC websites.
https://www.iec.ch/tc61/supportingdocuments
https://www.iec.ch/sc61c/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
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 can 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 Horizontal publications, basic safety publications and group safety
publications 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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.
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.

Part 2-118: Particular requirements for professional ice-cream makers

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of appliances for making ice cream and artisan
gelato exclusively operated by professional users.
Ice cream makers intended for professional use are employed in commercial environments,
such as restaurants, hotels, supermarkets, shops, as well as in preparation areas of bars,
bakeries, ice cream shops, institutional catering, and other similar professional settings.
Appliances taken into account are those intended for commercial use and similar appliances
not intended for normal household use but which may can nevertheless be a source of danger
to the public, such as appliances intended to be used by laymen in shops, stores, by artisans
or on farms, which rated voltage is not more than 250 V for single-phase appliances and 480 V
for other appliances.
Appliances covered by this standard are provided with a refrigerant condensing unit which is
usually incorporated, but for some appliances may can be remote.
As far as is practicable, this standard deals with the common hazards presented by these types
of appliances including those that use flammable refrigerants and appliances employing
R-744 refrigerant.
This standard is not applicable to appliances with a mass of flammable refrigerant exceeding
the limits specified in 22.112 or to appliances with that use refrigerants with a toxicity
classification of B according to ISO 817.
It does not cover those features of construction and operation of refrigerating appliances that
are dealt with in ISO standards.
This standard also applies to following types of appliances:
– mixers to make ice cream and similar pastry products in which, for the preparation of the
product, heating process is made within the appliance before the cooling process;
– appliances for storing whipping cream mix in a refrigerated tank and for whipping the cream
for the delivery process;
– freezers designed to produce soft ice cream and dispense it directly into containers;
– machines for soft-serve ice cream;
– batch dispensing freezers.
NOTE 101 Attention is drawn to the fact that:
– countries can have additional requirements for appliances incorporating pressure vessels;
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements can be necessary;
– in many countries, additional requirements are specified by the national health authorities,
the national authorities responsible for the protection of labour, the national water supply
authorities and similar authorities;
– for appliances or parts of appliances intended to be used outdoors, additional requirements
can be necessary.
This standard does not apply to:
– appliances with a refrigerating system operating with flammable refrigerant;
– split systems having a refrigerant charge of flammable refrigerant exceeding 150 g in any
refrigerating circuit;
– ice cream appliances for household use (IEC 60335-2-24);
– appliances intended exclusively for industrial purposes;
– 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).
