IEC 60335-2-71:2018 deals with the safety of all kinds of electrical heating appliances used for livestock rearing and breeding, such as: heat-radiating appliances, electrical sitting-hens, incubators, chicken breeding units and heating plates for animals, the rated voltage of the appliances being not more than 250 V for single-phase appliances and 480 V for other appliances. This standard applies to heating appliances used for livestock rearing and breeding that include an electrical motor. 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); - heating units embedded in the floor; - flexible sheet heating elements for room heating (IEC 60335-2-96); - room heaters (IEC 60335-2-30). 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. 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).

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.

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.

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.
