FOR HOUSEHOLD AND SIMILAR USE –

Part 1: General requirements
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 60730-1 has been prepared by IEC technical committee 72:
Automatic controls for household use.
This fourth edition cancels and replaces the third edition published in 1999, Amendment 1
(2003), and Amendment 2 (2007).
The main technical modifications of this standard since this previous publication are listed
below:
– changes to the low temperature test requirements for in-line cords;
– revision to the pollution degree for the environment surrounding contacts;
– addition of the use of screwless terminals on printed circuit boards and revisions to
creepage distances;
– additions of CISPR 11 EMC requirements;

60730-1 © IEC:2010 – 7 –
– incorporation of EMC test levels from IEC 60335 series;
– additional testing for flexible cords;
– revisions to the requirements for resistance to heat, fire and tracking including
replacement of Clause 21 and Annexes F and G;
– new Annex T for additional requirements for non-SELV supplied sensor cable or cord;
– new requirements in H.27.1 for first and second fault approach to ensure functional
safety;
– incorporation of software techniques from IEC 61508-3 in H.11.12;
– replacement of Annex D (Canada and USA) with a reference to UL 746C;
– updates to the references and bibliography;
– the keyword index was deleted as unnecessary due to the availability of search
functions for electronic editions of the standard.
The text of this standard is based on the following documents:
FDIS Report on voting
72/789/FDIS 72/790/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.
A list of all parts of the IEC 60730 series, under the general title: Automatic controls for
household and similar use, can be found on the IEC website.
In the development of a fully international standard to cover automatic controls for household
and similar use, it has been necessary to take into consideration the differing requirements
resulting from practical experience in various parts of the world and to recognize the variation
in national electrical systems and wiring rules.
The “in some countries” notes regarding differing national practices are contained in the
following subclauses:

It is envisaged that in the next edition of this standard it will be found possible to remove those
differences that are covered by new IEC standards now being prepared by other technical
committees.
This part 1 is to be used in conjunction with the appropriate part 2 for a particular type of
control, or for controls for particular applications. This part 1 may also be applied, so far as
reasonable, to controls not mentioned in a part 2, and to controls designed on new principles,
in which cases additional requirements may be considered to be necessary.
See also 4.3.5.2 and 4.3.5.3.
Where, for a particular clause or subclause, the text of part 2 indicates:
Addition: the part 1 text applies with the additional requirement indicated in a part 2;
Modification: the part 1 text applies with a minor change as indicated in a part 2;
Replacement: the part 2 text contains a change which replaces the part 1 text in its
entirety.
Where no change is necessary, the part 2 indicates that the relevant clause or subclause
applies.
NOTE In this standard the following print types are used:
– Requirements proper: in roman type.
– Test specifications: in italic type.
– Explanatory matter: in smaller roman type.

1 Scope and normative references
1.1 In general, this International Standard applies to automatic electrical controls for use in,
on, or in association with equipment for household and similar use, including controls for
heating, air-conditioning and similar applications. The equipment may use electricity, gas, oil,
solid fuel, solar thermal energy, etc., or a combination thereof.
1.1.1 This International Standard applies to the inherent safety; to the operating values,
operating times, and operating sequences where such are associated with equipment safety,
and to the testing of automatic electrical control devices used in, or in association with,
household or similar equipment.
This standard is also applicable to controls for appliances within the scope of IEC 60335-1.
This standard is also applicable to controls for building automation systems within the scope of
ISO 16484-2
Throughout this standard the word "equipment" means "appliance and equipment."
This standard does not apply to automatic electrical controls intended exclusively for industrial
applications unless explicitly mentioned in the relevant part 2.
This standard is also applicable to individual controls utilized as part of a control system or
controls which are mechanically integral with multifunctional controls having non-electrical
outputs.
Automatic electrical controls for equipment not intended for normal household use, but which
nevertheless may be used by the public, such as equipment intended to be used by laymen in
shops, in light industry and on farms, are within the scope of this standard.
See also Annex J.
This standard is also applicable to relays when used as controls for IEC 60335 appliances.
Additional requirements for the safety and operating values of relays when used as controls for
IEC 60335 appliances are contained in Annex U.
NOTE 1 These requirements are referred to by IEC 61810-1, Scope.
NOTE 2 This standard is intended to be used for the testing of any stand-alone relay which is intended to be used
as a control of an appliance according to IEC 60335-1. It is not intended to be used for any other stand-alone relay,
or to replace the IEC 61810 series of standards.
1.1.2 This standard applies to automatic electrical controls, mechanically or electrically
operated, responsive to or controlling such characteristics as temperature, pressure, passage
of time, humidity, light, electrostatic effects, flow, or liquid level, current, voltage, acceleration,
or combinations thereof.
1.1.3 This standard applies to starting relays, which are a specific type of automatic electrical
control, intended to switch the starting winding of a motor. Such controls may be built into, or
be separate from, the motor.

1.1.4 This standard applies to manual controls when such are electrically and/or mechanically
integral with automatic controls.
Requirements for manual switches not forming part of an automatic control are contained in IEC 61058-1.
1.2 This standard applies to controls with a rated voltage not exceeding 690 V and with a
rated current not exceeding 63 A.
1.3 This standard does not take into account the response value of an automatic action of a
control, if such a response value is dependent upon the method of mounting the control in the
equipment. Where a response value is of significant purpose for the protection of the user, or
surroundings, the value defined in the appropriate household equipment standard or as
determined by the manufacturer shall apply.
1.4 This standard applies also to controls incorporating electronic devices, requirements for
which are contained in Annex H.
This standard applies also to controls using NTC or PTC thermistors, requirements for which
are contained in Annex J.
