Overview

IEC 60335-2-42:2002+AMD1:2008 CSV is an international standard published by the International Electrotechnical Commission (IEC). It sets out specific safety requirements for electrically operated commercial forced convection ovens, steam cookers, steam-convection ovens, and steam generators intended for use in commercial settings. The standard is designed to reduce hazards associated with these appliances in professional environments such as restaurants, canteens, hospitals, bakeries, and butcheries. It covers appliances operating at voltages up to 250 V for single-phase and up to 480 V for other appliances. The scope specifically excludes appliances for purely industrial use, those designed for hazardous atmospheres, continuous process food production, and microwave ovens.

Key Topics

• Appliance Types: Focus on forced convection ovens, steam cookers, steam-convection ovens, and associated steam generators used in commercial cooking.
• Safety Protection: Addresses protection against electrical shock, thermal, mechanical, fire, and radiation hazards, including considerations for both normal and abnormal operational situations.
• Marking and Instructions: Requires detailed marking on appliances regarding pressures, installation procedures, and specific instructions to prevent misuse and ensure safe operation-especially warnings to prevent scalding.
• Protection Ratings: Stipulates ingress protection (IP) levels for appliances, with higher protection required for equipment exposed to water or installed in demanding environments.
• Testing Methods: Outlines testing norms for assessing electrical, mechanical, and thermal safety, including splash tests for moisture resistance.
• Installation Requirements: Considers appliances installed as part of a system (e.g., in a series/bank or attached to installation walls) and prescribes provisions to prevent electric shock and water ingress.

Applications

This standard is essential for manufacturers, importers, test laboratories, and regulatory authorities involved in the design, production, and assessment of commercial kitchen appliances powered by electricity. IEC 60335-2-42 applies to:

• Restaurant and Catering Equipment: Ensures commercial ovens and steam cookers meet rigorous safety standards required in fast-paced, high-use environments.
• Healthcare and Institutional Kitchens: Used for food preparation equipment in hospitals, schools, and care facilities where safety is paramount.
• Bakeries and Food Processing: Applicable to ovens and steam equipment used in commercial bakeries, butcheries, and other food preparation businesses.
• Product Certification and Compliance: Provides a basis for national and international certification, supporting market access and compliance with legal or insurance requirements.

The standard ensures that equipment is not only safe for normal use but also prepared for foreseeable abnormal conditions, helping to minimize risks of injury, equipment damage, and business interruption.

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.
This part of International Standard IEC 60335 has been prepared by IEC subcommittee 61E:

– 4 – 60335-2-42 © IEC:2002+A1:2008
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 electric
forced convection ovens, steam cookers and steam-convection ovens.
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 of Part 1 concerns an adjective, the
adjective and the associated noun are also in bold .
The following differences exist in the countries indicated below.
– 6.1: Class 01 appliances are allowed (Japan).
– 6.2: For appliances intended to be installed in a kitchen, an appropriate degree of protection against harmful
ingress of water is required according to their height of installation (France).
– 13.2: Leakage current limits are different (Japan).
– 16.2: Leakage current limits are different (Japan).
– Clause 21: For appliances intended to be installed in a kitchen, different values of impact energy are
applicable according to the height of the impact point (France).
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.
NOTE 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 the amendment 1 be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.

IMPORTANT – The “colour inside” logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this publication using a colour printer.

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.

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrically operated commercial forced
convection ovens, steam cookers, steam-convection ovens and, exclusive of any other
use, steam generators, not intended for household use, 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.
NOTE 101 These appliances are used for example in restaurants, canteens, hospitals and commercial enterprises
such as bakeries, butcheries, etc.
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.
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 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.
NOTE 103 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);
– continuous process appliances for the mass production of food;
– microwave ovens (IEC 60335-2-90);

normal operation
operation of the appliance under the following conditions
ƒ Dry heat mode
The appliance is operated with all the shelves or the shelf trolley in position according to the
manufacturer's instructions but with no load. The controls are set so that the mean value
of the temperature over the thermostat cycle at the geometric centre of each usable space in
the interior of the oven is maintained at 220 °C ± 4 °C. Stepped controls are set so that this
temperature is 220 °C ± 15 °C.
For ovens that are unable to attain a temperature of 220 °C, the controls are set at the
maximum.
For ovens that are capable of attaining temperatures in excess of 270 °C, the controls are set
so that the mean value of the temperature is 50 °C ± 4 °C below the maximum temperature
attainable.
ƒ Steaming only mode
The appliance is operated in accordance with the manufacturer's instructions with all controls
intended to be operated by the user adjusted to their maximum setting until reaching
operating temperature. They are then readjusted, if possible, to the lowest setting that
maintains that temperature.
Appliances with steam generators intended to be filled by hand or by a manually operated
tap are filled to the indicated level on the steam generator.
Appliances with steam generators intended to be filled automatically are connected to a
water supply having the pressure designated by the manufacturer. Where the manufacturer
specifies a range of pressures, the pressure is adjusted to give the most unfavourable
conditions.
The incoming water is maintained at
– 15 °C ± 5 °C in the case of appliances intended for connection to a cold water supply;
– 60 °C ± 5 °C or the temperature indicated in the instruction sheet, whichever is the higher,
in the case of appliances intended for connection to a hot water supply only.
NOTE 101 If the appliance is intended for connection to either a hot or cold water supply, the temperature of the
water is that which gives the most unfavourable results.
Lids, doors, and covers are in position and closed.
The cooking compartment of the appliance contains a water load, initially at 15 °C ± 5 °C,
comprising 0,5 l/kg of the manufacturer's declared maximum food load. The water load is
evenly distributed between the shelves or pans.
NOTE 102 Since pans may be perforated to allow for circulation of steam, the water load may be contained in
suitable containers evenly distributed over the shelves or pans.
ƒ Combination mode
The appliance is operated as for the steaming only mode but with the forced convection fan/s
and elements for heating the cooking compartment on and the temperature controls set as
for the dry heat mode.
In all the above cases, motors incorporated in the appliance are operated in the intended
manner under the most severe conditions that can be expected in normal use, taking into
account the manufacturer's instructions.

11.2 Addition:
Appliances intended to be fixed to the floor and appliances with a mass greater than 40 kg
and not provided with rollers, castors or similar means are installed in accordance with the
manufacturer's instructions. If no instructions are given, these appliances are considered as
appliances normally placed on the floor.
Separate cooking compartments and steam generators are assembled in accordance with
the manufacturer's instructions and located in the test corner in such a manner that they will
have the most unfavourable effect on each other and on their surroundings.
11.4 Replacement:
Appliances are operated under normal operation such that the total power input of the
appliance is 1,15 times rated power input. If it is not possible to switch on all heating elements at
the same time, the test is made with each of the combinations that the switch arrangement will
allow, the highest load possible with each switching arrangement being in circuit.
If the appliance is provided with a control that limits the total power input, the test is made
with whichever combination of heating units, as may be selected by the control, imposes the
most severe condition.
If the temperature rise limits of motors, transformers or electronic circuits are exceeded, the
test is repeated with the appliance supplied at 1,06 times rated voltage. In this case only
the temperature rises of motors, transformers or electronic circuits are measured.
11.7 Replacement
The appliance is operated as follows.
Appliances with steam generators incorporated in the cooking compartment are operated
on continuous cycles until steady conditions are established. Each cycle comprises an
operating period followed by a rest period strictly sufficient, but in no case longer than 5 min,
to allow for replacing the water load, the water level in the steam generators intended to be
filled by hand being, if necessary, restored to the indicated level, in accordance with the
manufacturer's instructions.
The operating period is equal to the maximum cooking time declared by the manufacturer or,
if such declaration is not provided, to the time taken for the appliance to reach the maximum
temperature conditions.
Appliances with separate steam generators are switched on and allowed to operate until
steady conditions are established in the steam generator. When these conditions have been
reached, the appliance is operated as above.
Other appliances are operated until steady conditions are established.
NOTE 101 The duration of the test may consist of more than one cycle of operation.
11.8 Addition:
During the test the pressure relief device shall not operate.

A litre of cold water containing approximately 1 % NaCl is poured steadily over a period of
1 min over the bottom surface of the cooking compartment.
The water containers of appliances intended to be filled with water by hand are completely
filled with water and a further quantity equal to 15 % of the capacity of the container is poured
in steadily over a period of 1 min.
Appliances with containers intended to be filled by a manually operated tap or automatically
are connected to a water supply having the maximum supply pressure indicated by the
manufacturer. The means for controlling the incoming water is held fully open and the filling
continued for 1 min after the first evidence of overflow, or until a further protective system
operates to stop the inflow.
In addition, forced convection ovens with automatic fillers or spraying systems and intended
for permanent connection to the water mains, are operated for 5 min with any means that limit
the water intake, for example a water level device, flow control, etc., rendered inoperative in
the most unfavourable conditions. The fan motor is operated, if it can be operated
independently, with the heating elements on or not, whichever is the most severe condition.
During this test the appliance is connected to a water supply (without salt) having the
maximum pressure indicated by the manufacturer.
If more than one controlling device is fitted, the test is repeated with each device rendered
inoperative in turn.
The appliance shall withstand an electric strength test as specified in 16.3 and inspection
shall show that water that may have entered the appliance does not impair compliance with
this part: in particular, there shall be no trace of water on insulation for which clearances and
creepage distances are specified in Clause 29.
15.3 Addition:
NOTE 101 If it is not possible to place the whole appliance in the humidity cabinet, parts containing electrical
components are tested separately, taking into account the conditions that occur in the appliance.
15.101 Appliances that are provided with a tap intended for filling or cleaning, shall be
constructed so that the water from the tap cannot come into contact with live parts.
Compliance is checked by the following test.
The tap is fully opened for 1 min with the appliance connected to a water supply having the
maximum water pressure indicated by the manufacturer. Tiltable and movable parts, including
lids, are tilted or placed in the most unfavourable positions. Swivelling outlets of water taps
are so positioned as to direct water on to those parts that will give the most unfavourable
result. Immediately following this treatment the appliance shall withstand an electric strength
test as specified in 16.3.
