Part 2-49: Particular requirements for commercial electric
appliances for keeping food and crockery warm

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 shall
not be held responsible for identifying any or all such patent rights.
This consolidated version of the official IEC Standard and its amendment has been prepared
for user convenience.
IEC 60335-2-49 edition 5.1 contains the fifth edition (2021-11) [documents 61/6365/FDIS and
61/6411/RVD] and its amendment 1 (2025-08) [documents 61/7460/FDIS and 61/7490/RVD].
In this Redline version, a vertical line in the margin shows where the technical content is
modified by amendment 1. Additions are in green text, deletions are in strikethrough red text.
A separate Final version with all changes accepted is available in this publication.

IEC 60335-2-49 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.

FDIS Report on voting
61/6365/FDIS 61/6411/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 in the IEC 60335 series, published 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 unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) 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: Particular requirements for commercial electric
appliances for keeping food and crockery warm.
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 and its amendment will remain
unchanged until the stability date indicated on the IEC website under webstore.iec.ch in the
data related to the specific document. At this date, the document will be
– reconfirmed,
– withdrawn, or
– revised.
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).
– 13.2: Leakage current limits are different (Japan).

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 supporting documents on the IEC website:
https://www.iec.ch/tc61/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 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 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.
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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods for 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.

1 Scope
This clause of Part 1 is replaced by the following:
This part of IEC 60335 deals with the safety of electrically operated commercial appliances for
keeping food and crockery warm, their rated voltage being not more than 250 V for single-
phase appliances connected between one phase and neutral, and 480 V for other appliances.
Examples of appliances that are within the scope of this standard are:
– hot cupboards, with or without heated tops;
– heated tops;
– heated display cases;
– heated crockery dispensers;
– heated tables;
– radiant heaters.
These appliances are not intended for household and similar purposes. They are used for
commercial purposes, processing of food, also in areas open to the public, for example in
kitchens of restaurants, canteens, hospitals and in commercial enterprises, such as bakeries
and butcheries.
These appliances are not intended for household and similar purposes. They are used:
– by experts or instructed persons for commercial processing of food in areas that are not
areas open to the public, for example in kitchens of restaurants, canteens, hospitals and
in commercial enterprises such as bakeries and butcheries; or
– by laypersons in areas open to the public, for example hotel/motel common areas,
canteens and self-service restaurants.
The electrical part of appliances making use of other forms of energy is also within the scope
of this standard.
As far as is practicable, this standard deals with the common hazards presented by these types
of appliances.
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;
– in many countries, additional requirements are specified for pressure appliances.
This standard does not apply to:
– appliances designed 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);
– appliances for continuous mass production of food;
– commercial electric bains-marie (IEC 60335-2-50);
– battery-operated appliances;
– warming plates and similar appliances for household use covered by IEC 60335-2-12 used
in the following environments by laymen:
• staff kitchen areas in shops, offices and other working environments;
• farm houses;
• hotels rooms, motels rooms and other residential type environments;
• bed and breakfast type environments.

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 applicable except as follows.
9.101 Fan motors providing a cooling effect in order to comply with the requirements of
Clause 11 shall start under all voltage conditions that can occur in use.
Compliance is checked by the following tests using a supply source such that its drop in voltage
does not exceed 1 % during the tests. The appliance is returned to room temperature after
each test.
The appliance is started under the conditions occurring at the beginning of normal operation or,
for automatic appliances, at the beginning of the normal cycle of operation, a voltage equal to
0,85 times rated voltage being applied to the input terminals of the appliance.
For appliances provided with motors having other than centrifugal starting switches, this test is
repeated at a voltage equal to 1,06 times rated voltage being applied to the input terminals of
the appliance.
The tests are carried out three times.
In all cases, the motor shall start and it shall function in such a way that safety is not affected
and overload protective devices of the motor shall not operate.
10 Power input and current
This clause of Part 1 is applicable except as follows.
10.1 Modification:
Instead of the first paragraph of the requirement, the following applies:
The power input of appliances without induction heating sources, at rated voltage and at
normal operating temperature, shall not deviate from the rated power input by more than the
deviation shown in Table 1.
The power input of appliances having only induction heating sources, at rated voltage and
at normal operating temperature, shall not deviate from the rated power input by more than
10 %.
The measurement is made before the controls are adjusted to the reduced setting.
For appliances incorporating induction heating sources and non-induction heating sources,
the following applies:
The power input of the induction heating sources and the non-induction heating sources is
measured separately, in each case using a combination of heating units that can be on at the
same time to give the highest power input. For the induction heating sources, the
measurement is made before the controls are adjusted to the reduced setting.
For induction heating sources, the power input so measured shall not deviate from the rated
power input marked or declared by the manufacturer (see 7.1) by more than 10 % and in the
case of non-induction heating sources deviate from the rated power input marked or declared
by the manufacturer (see 7.1) by more than the deviation shown in Table 1 for heating
appliances.
In addition, the power input of the appliance when the induction heating sources and non-
induction heating sources are operated simultaneously shall not deviate from the rated power
input by more than 10 %.
Addition:
For appliances having more than one heating unit, the total power input may be determined
by measuring the power input of each heating unit separately (see also 3.1.4).
10.2 Modification:
Instead of the first paragraph of the requirement, the following applies:
The current of appliances without induction heating sources, at rated voltage and at normal
operating temperature, shall not deviate from the rated current by more than the deviation
shown in Table 2.
For appliances incorporating induction heating sources and non-induction heating sources,
the following applies.
The current of the induction heating sources and the non-induction heating sources is
measured separately, in each case using a combination of heating units that can be on at the
same time to give the highest current. For the induction heating sources, the measurement
is made before the controls are adjusted to the reduced setting.
For non-induction heating sources, the current so measured shall not deviate from the rated
current marked or declared by the manufacturer (see 7.1) by more than the deviation shown in
Table 2 for heating appliances.

Part 2-49: Particular requirements for commercial electric
appliances for keeping food and crockery warm

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.
IEC 60335-2-49 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This fifth edition cancels and replaces the fourth edition published in 2002, Amendment 1:2008
and Amendment 2:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the text has been aligned with IEC 60335-1:2020;
b) introduction of requirements for appliances intended for use in areas open to the public,
including external accessible surface temperatures (Clause 1, 7.12, 11.8, Table 102);
c) exclusion of battery-operated appliances (Clause 1);
d) clarification of applicable standard for appliances for use by laymen (Clause 1, 7.12);

e) relocation of cleaning instructions from 7.12.1 to 7.12;
f) relocation of 24.101 to 22.106;
g) conciliation of the text of IEC 60335-2-49 with other standards under IEC/TC61/MT32;
h) some notes have been converted to normative text, modified or deleted (Clause 1, 7.1, 7.15,
11.3, 11.7, 15.2, 19.2, 22.101, 23.3);
i) additional requirements for measurement of input current;
j) clarification of the testing procedure in 15.1.1;
k) clarification of the test conditions in 20.1 and 23.3;
l) clarifications of the requirements in 25.3.
The text of this International Standard is based on the following documents:
FDIS Report on voting
61/6365/FDIS 61/6411/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 in the IEC 60335 series, published 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

preclude it is used. It was established on the basis of the sixth edition (2020) 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: Particular requirements for commercial electric
appliances for keeping food and crockery warm.
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.

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 supporting documents on the IEC website:
https://www.iec.ch/tc61/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 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 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.
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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods for 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.

appliances for keeping food and crockery warm

1 Scope
This clause of Part 1 is replaced by the following:
This part of IEC 60335 deals with the safety of electrically operated commercial appliances for
keeping food and crockery warm, their rated voltage being not more than 250 V for single-
phase appliances connected between one phase and neutral, and 480 V for other appliances.
Examples of appliances that are within the scope of this standard are:
– hot cupboards, with or without heated tops;
– heated tops;
– heated display cases;
– heated crockery dispensers;
– heated tables;
– radiant heaters.
These appliances are not intended for household and similar purposes. They are used for
commercial purposes, processing of food, also in areas open to the public, for example in
kitchens of restaurants, canteens, hospitals and in commercial enterprises, such as bakeries
and butcheries.
The electrical part of appliances making use of other forms of energy is also within the scope
of this standard.
As far as is practicable, this standard deals with the common hazards presented by these types
of appliances.
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;
– in many countries, additional requirements are specified for pressure appliances.
This standard does not apply to:
– appliances designed 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);
– appliances for continuous mass production of food;
– commercial electric bains-marie (IEC 60335-2-50);
– battery-operated appliances;

– warming plates and similar appliances for household use covered by IEC 60335-2-12 used
in the following environments by laymen:
• staff kitchen areas in shops, offices and other working environments;
