Part 2-71: Particular requirements for electrical heating appliances
for breeding and rearing animals

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.
International Standard IEC 60335-2-71 has been prepared by subcommittee 61H: Safety of
electrically-operated farm appliances, of IEC technical committee 61: Safety of household and
similar electrical appliances.
This third edition cancels and replaces the second edition published in 2002, its Amendment 1
(2007) and its Amendment 2 (2012). This edition constitutes a technical revision.

– 4 – IEC 60335-2-71:2018 © IEC 2018
This edition includes the following significant technical changes with respect to the previous
edition:
– two paragraphs are deleted (Introduction);
– normative references updated (Clause 2);
– colour required for symbols (7.6);
– some notes converted to normative text (19.2, 21.101, 22.104).
The text of this International Standard is based on the following documents:
FDIS Report on voting
61H/348/CDV 61H/357/RVC
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
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.
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 fifth edition (2010) 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 electrical heating
appliances for breeding and rearing animals.
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
associated noun are also in bold.
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 committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
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 document 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.

For protective screens, the width of mesh shall not exceed 25 mm and shall not be less than
10 mm.
Compliance is checked by inspection, measurement, a manual test and the salt mist test
described in IEC 60068-2-11, test Ka, which is made with the grid kept in the test chamber for
7 days (168 h).
A 50 mm square probe shall not penetrate with its whole cross-section into the protective grid
when a force of 20 N is applied.
22.104 Portable heat-radiating appliances that are not operated on the floor in normal use
shall be provided with a means of suspension that allows the height of suspension to be
varied.
The means of suspension shall be so designed that loosening or accidental altering of the
setting cannot occur. This requirement may be met by the use of closed hooks (spring safety
hooks) or eyes. Hooks whose projection onto a plane surface shows a closed circle are
considered closed.
The means of suspension shall:
– be delivered complete, including the fixing means for mounting the appliance at the place
of use, including ceiling hooks and the like;
– not be the supply cord;
– be so designed and dimensioned, that it is able to support a mass five times the mass of
the appliance, or 20 kg, whichever is larger;
– be at least 2 m long;
– be of a material that is resistant to corrosion and fire.
Compliance is checked by inspection, measurement and by the following tests.
The heat-radiating appliance is fixed by its means of suspension in accordance with the
manufacturer's instructions. A load is applied to the body of the appliance so that the load on
the means of suspension is five times the mass of the appliance or 20 kg, whichever is larger.
The load is applied gradually and maintained for 1 min, after which it is removed.
The suspension system shall not break.
One of the additional samples of the means of suspension is subjected to the salt mist test
described in IEC 60068-2-11, test Ka, which is made with the means of suspension mounted
as in normal use; it is kept in the test chamber for 7 days (168 h).
After the test, the means of suspension shall show no sign of deterioration that could affect
compliance with this standard, and its coating, if any, shall not have loosened from the metal
surface and shall not have been pieced.
The other additional sample of the means of suspension, if of non-metallic material, shall be
subjected to the glow-wire test of IEC 60695-2-11 which is carried out at 850 °C.
During the application and after the removal of the glow-wire tip, there shall be no ignition of
the means of suspension.

22.105 The clearance between the windings of tubular heating elements that, for example,
may be spirally coiled, shall not be less than 10 mm.
Compliance is checked by inspection and measurement.
22.106 Heat-radiating appliances shall not concentrate heat at any point more than
500 mm from the element.
Compliance is checked by inspection and measurement.
Temperatures measured at distances greater than 500 mm from the element shall not exceed
the values measured at a distance of 500 mm from the element.
22.107 Thermal cut-outs that operate during the test of 19.4 shall be non-self-resetting
thermal cut-outs. If the thermal cut-out is of the manual resetting type, then it shall have a
trip-free operation.
Compliance is checked by inspection and by manual test.
