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 60335-2-47 has been prepared by IEC technical committee 61: Safety of household and

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.
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 part of IEC 60335 deals with the safety of electrically operated commercial boiling pans,
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.
These appliances are not intended for household and similar purposes. They are used for
commercial processing of food in areas not 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;
– battery-operated appliances.

11.3 Addition:
Where the external accessible surfaces are suitably flat and access permits, then the test
probe of Figure 101 is used to measure the temperature rises of external accessible surfaces
specified in Table 101. The probe is applied with a force of 4 N ± 1 N to the surface in such a
way that the best possible contact between the probe and the surface is ensured. The
measurement is performed after a contact period of 30 s.
The probe may be held in place using a laboratory stand clamp or similar device. Any measuring
instrument giving the same results as the probe may be used.
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
unfavourable 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 rise of the components for which the temperature rise limits were exceeded are
measured.
11.7 Replacement:

Steady conditions are considered to exist 60 min after reaching the temperatures defined for
normal operation.
When an appliance is assembled in combination with, equipped with or incorporating
accessories or other appliances, the interaction shall be covered if they are provided to operate
simultaneously as stated by the manufacturer or by a common control.
Agitator motors are operated continuously unless provided with a timer, in which case they are
operated for the maximum time allowed by the timer, or until steady conditions are established,
whichever is the shortest.
Tilting motors are operated immediately after the appliance has reached steady conditions, for
one full cycle of operation (one cycle being from the fully up position to the fully down position
and back to the fully up position).
Lifting motors are similarly operated, but for three such cycles.
11.8 Modification:
During the test, the temperature rises are monitored continuously and shall not exceed the
values shown in Table 3 and Table 101.
Addition:
During the test, the pressure relief device shall not operate.
