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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

International Standard IEC 60335-2-118 has been prepared by subcommittee 61C: Safety of
refrigeration appliances for household and commercial use, of IEC technical committee 61:
Safety of household and similar electrical appliances.
The text of this International Standard is based on the following documents:
CDV Report on voting
61C/798/CDV 61C/823A/RVC
Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
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 latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fifth edition (2010) of that standard.

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 professional ice-cream makers.
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 small 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.

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.
HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES – SAFETY

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

product, an 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.
NOTE 101 Attention is drawn to the fact that:
– 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.
This standard does not apply to:
– appliances with a refrigerating system operating with flammable refrigerant;
– ice cream appliances for household use (IEC 60335-2-24);
– appliances intended exclusively for industrial purposes;

The temperature of ballast windings and their associated wiring shall not exceed the values
specified in 12.4 of IEC 60598-1:2014, when measured under the conditions stated.
11.101  lf the temperature of any parts of the appliance is higher than the required limits given
in 11.8, the test is performed again, the thermostats or similar control devices being set at the
lowest temperature with the short-circuit removed.
11.102  Heating systems incorporated in appliances shall not give rise to excessive
temperatures.
Compliance is checked by the following test:
Heating systems are energised as follows:
– for compression-type appliances in which the heating system can be energised with the
rest of the appliance non energised, the supply voltage is as specified in 11.4;
– for other compression-type appliances, the supply voltage is as specified in 11.6.
The test is continued until steady conditions are established.
Temperature rises are measured by means of thermocouples fixed on the outside surface of
the insulation of the heating systems. Temperature rises shall not exceed the values given in
11.8.
11.103 Ancillary heating elements are energised, with the refrigerating system switched off,
if this is possible in normal use. They are supplied at 1,15 times their power input rating, until
steady conditions are reached.
Temperature rises are measured by thermocouples fixed on the outside surface of the insulation
of the ancillary heating element.
Temperature rises shall not exceed the values specified in 11.8.

15.2 Addition:
Furthermore, if the inspection shows that water is in contact with the defrost heating element
or its insulation, then the apparatus shall withstand the test of 22.102.
15.101 For appliances which are directly connected to the water supply, the container, or that
part of the appliance which serves as the container, is filled with water as in normal use. The
inlet valve is then held open and the filing is continued for 1 min after the first evidence of
overflow.
Where no spillage occurs due to operation of a device that prevents such spillage, the inlet
valve is held open for a further 5 min following the operation of this device.
Immediately after the test, the appliance shall withstand the electric strength test of 16.3 and
inspection shall show that there is no trace of water on insulation which could result in a
reduction of creepage distances and clearances below the values specified in Clause 29.
15.102 Appliances, other than built-in appliances, are tilted at an angle of up to 2° the position
of normal use in the direction which is likely to be the most unfavourable for this test.
The appliance is disconnected from the supply and the controls are set to the on position. From
a height of approximately 50 mm, 0,5 l of the solution as specified in 15.2 is poured uniformly
in approximately 60 s over any surfaces with less than 2° inclination to the horizontal. Only
surfaces measuring more than 60 mm in at least one direction, and less than 2,2 m above the
floor are taken into consideration.
Immediately after the test, the appliance shall withstand the electric strength test of 16.3 and
inspection shall show that there is no trace of water on insulation which could result in a
reduction of clearances and creepage distances below the values specified in Clause 29.
