IEC 60730-2-7:2008

Automatic electrical controls for household and similar use - Part 2-7: Particular requirements for timers and time switches

IEC 60730-2-7:2008 applies to timers and time switches for household and similar use that may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof, including heating, air conditioning and similar applications. This second edition cancels and replaces the first edition published in 1990 and its Amendment 1 (1994). This second edition constitutes a technical revision. This new edition incorporates requirements for tungsten filament lamp loadings as well as updates the standard to IEC 60730-1:1999, Amendment 2 (2007). This Part 2-7 is to be used in conjunction with IEC 60730-1. It was established on the basis of the third edition of that standard (1999) and its Amendment 1 (2003) and Amendment 2 (2007). Consideration may be given to future editions of, or amendments to, IEC 60730-1.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60730-2-7 has been prepared by IEC technical committee 72:
Automatic controls for household use.
This second edition cancels and replaces the first edition published in 1990 and its
Amendment 1 (1994). This second edition constitutes a technical revision. This new edition
incorporates requirements for tungsten filament lamp loadings as well as updates the
standard to IEC 60730-1:1999, Amendment 2 (2007).
The text of this standard is based on the following documents:
FDIS Report on voting
72/760/FDIS 72/764/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 2-7 is to be used in conjunction with IEC 60730-1. It was established on the basis of
the third edition of that standard (1999) and its Amendment 1 (2003) and Amendment 2
(2007). Consideration may be given to future editions of, or amendments to, IEC 60730-1.
This Part 2-7 supplements or modifies the corresponding clauses in IEC 60730-1 so as to
convert that publication into the IEC standard: Particular requirements for timers and time
switches.
