Household and similar electrical appliances - Safety -- Part 2-89: Particular requirements for commercial refrigerating appliances with an incorporated or remote refrigerant condensing unit or compressor
This clause of Part 1 is replaced by the following. This International Standard specifies safety requirements for electrically operated commercial refrigerating appliances that have an incorporated compressor or that are supplied in two units for assembly as a single appliance in accordance with the manufacturer’s instructions (split system).
NOTE 101 Examples of appliances that are within the scope of this standard are
– refrigerated display and storage cabinets;
– refrigerated trolley cabinets;
– service counters and self-service counters;
– blast chillers and blast freezers.
As far as is practicable, this standard deals with the common hazards presented by these types of appliances. It does not cover those features of construction and operation of refrigerating appliances which are dealt with in ISO standards. NOTE 102 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;
– in many countries, additional requirements are specified by national authorities.
NOTE 103 This standard does not apply to
– domestic refrigerating appliances (IEC 60335-2-24)
– industrial refrigerating systems;
– motor-compressors (IEC 60335-2-34);
– commercial dispensing appliances and vending machines (IEC 60335-2-75);
– commercial ice-cream appliances;
– commercial ice makers;
– cold temperature rooms;
– multiple refrigerated chambers with a remote compressor.
NOTE 104 Appliances with a charge of more than 150 g of flammable refrigerant in each separate refrigerant circuit are not covered by this standard. For appliances with a charge greater than 150 g of flammable refrigerant in each refrigerant circuit and for the installation, ISO 5149 may be applied. Consequently, such appliances cannot be assessed for safety using this part 2.

Introduction
p Add:
An investigation by CENELEC TC 61 has shown that all risks from products within the scope of this
standard are fully covered by the Low Voltage Directive, 2006/95/EC. For products having mechanical
moving parts, a risk assessment in accordance with the Machinery Directive, 2006/42/EC, has shown that
the risks are mainly of electrical origin and consequently this directive is not applicable. However, the
relevant essential safety requirements of the Machinery Directive are covered by this standard together
with the principal objectives of the Low Voltage Directive.

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 rights. IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by subcommittee 61C:
Household appliances for refrigeration, of IEC technical committee 61: Safety of household
and similar electrical appliances.
This second edition cancels and replaces the first edition published in 2002 including its
Amendment 1 (2005) and amendment 2 (2007). It constitutes a technical revision.
The principal changes in this edition as compared with the first edition of IEC 60335-2-89 are
as follows (minor changes are not listed):
– aligns the text with IEC 60335-1, and its Amendments 1 and 2;
– introduces requirements for appliances using transcritical refrigerant systems (3.107,
3.108, 3.109, 3.110, 3.111, 7.1, 7.6, 7.12.1, 22.103, 24.1.4, 24.102)
– introduces an enhanced flexing test (23.3)

The text of this standard is based on the following documents:
FDIS Report on voting
61C/208/FDIS 61C/211/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
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 fourth edition (2001) 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 commercial
refrigerating appliances with an incorporated or remote refrigerant unit or compressor.
Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. Where 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.
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.
The committee has decided that the contents of this publication will remain unchanged until
the stability 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.
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.

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 which 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 2-89: Particular requirements for commercial refrigerating appliances
with an incorporated or remote refrigerant unit or compressor
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard specifies safety requirements for electrically operated commercial
refrigerating appliances that have an incorporated compressor or that are supplied in two
units for assembly as a single appliance in accordance with the manufacturer’s instructions
(split system).
NOTE 101 Examples of appliances that are within the scope of this standard are
– refrigerated display and storage cabinets;
– refrigerated trolley cabinets;
– service counters and self-service counters;
– blast chillers and blast freezers.
As far as is practicable, this standard deals with the common hazards presented by these
types of appliances.
It does not cover those features of construction and operation of refrigerating appliances
which are dealt with in ISO standards.
NOTE 102 Attention is drawn to the fact t
