SAFETY OF HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –

Part 2-36: Particular requirements for commercial electric

cooking ranges, ovens, hobs and hob elements

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60335-2-36 has been prepared by subcommittee 61E: Safety of
electrical commercial catering equipment, of IEC technical committee 61: Safety of household
and similar electrical appliances.
It forms the fourth edition of IEC 60335-2-36 and replaces the third edition, published in
1993, its amendment 1 (1996) and amendment 2 (1998).

The text of this standard is based on the third edition, amendments 1 and 2 and the following
documents:
FDIS Report on voting
61E/347/FDIS 61E/361/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 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 third edition (1991) of that standard.

This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert it into the IEC standard: Safety requirements for commercial electric cooking ranges,
ovens, hobs and hob elements.
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 1 The following print types are used:

– ;
requirements: in roman type
test specifications: in italic type;
–
– notes: in small roman type.
bold
Words in in the text are defined in clause 2.
NOTE 2 Subclauses, notes and figures which are additional to those in part 1 are numbered starting from 101.
A bilingual version of this standard may be issued at a later date.

SAFETY OF HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –

Part 2-36: Particular requirements for commercial electric

cooking ranges, ovens, hobs and hob elements

1 Scope
This clause of part 1 is replaced by:

This standard deals with the safety of electrically operated commercial cooking ranges,
ovens, hobs, hob elements and similar appliances 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 1 These appliances are used for example in kitchens such as 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.
So far as is practicable, this standard deals with the common hazards presented by these
types of appliances.
NOTE 2 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;
– for appliances intended to be used in tropical countries, special 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.
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;
– steam-convection ovens;
– forced convection ovens (IEC 60335-2-42);

– steam cookers (IEC 60335-2-46);
– hot cupboards (IEC 60335-2-49).
2 Definitions
This clause of part 1 is applicable except as follows.
2.2.4 Addition:
NOTE The rated power input is the sum of the power inputs of all the individual elements in the appliance which
can be on at one time; where several such combinations are possible, that giving the highest power input is used in
determining the rated power input.

2.2.9 Replacement:
normal operation
: Operation of the appliance under the following conditions:

– Solid hob elements are operated with no load and sheathed hob elements are operated

with a load made of dull black, cold or hot rolled steel, 9 mm to 10 mm thick, which covers

not less than 90 % and not more than 100 % of the element surface. The hob elements

are operated with the controls set to give the temperatures as set out below, the
