IEC 60730-2-9:2008

Automatic electrical controls for household and similar use - Part 2-9: Particular requirements for temperature sensing controls

IEC 60730-2-9:2008 applies to automatic electrical temperature sensing controls for use in, on or in association with equipment for household and similar use, including electrical 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. This third edition cancels and replaces the second edition published in 2000, its Amendment 1 (2002) and Amendment 2 (2004) and constitutes a technical revision. This edition of IEC 60730-2-9 contains a new Annex EE, which is an informative guide to the application of temperature sensing controls. Additionally, a new requirement to 17.3.1 (there is an error in the FDIS document - 17.7.3 should be 17.3.1) was added to address the endurance requirement for temperature sensing devices where the whole control is declared as the sensing element for ambient temperatures below 0 °C. This document contains also some editorial changes due to new editions of referenced standards. This publication is to be read in conjunction with  IEC 60730-1:2010. 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.

Dispositifs de commande électrique automatiques à usage domestique et analogue - Partie 2-9: Règles particulières pour les dispositifs de commande thermosensibles

La CEI 60730-2-9:2008 s'applique aux dispositifs de commande électrique automatiques thermosensibles pour usage dans, sur ou en association avec des appareils à usage domestique et analogue, y compris les dispositifs de commande électrique pour le chauffage, le conditionnement d'air et applications analogues. Le matériel peut fonctionner à l'électricité, au gaz, au pétrole, aux combustibles solides, à l'énergie solaire, etc., ou à une de leurs combinaisons. Cette troisième édition annule et remplace la seconde édition publiée en 2000 et ses Amendement 1 (2002) et Amendement 2 (2004), et constitue une révision technique. Cette édition de la CEI 60730-2-9 comprend une nouvelle Annexe EE, qui est un guide informatif pour l'application des dispositifs de commande thermosensibles. De plus, une nouvelle exigence en 17.3.1 a été ajoutée pour traiter de l'exigence d'endurance pour les dispositifs thermosensibles dans lesquels la totalité du dispositif de commande est déclarée comme élément sensible pour des températures de fonctionnement inférieures à 0 °C. Ce document contient également quelques modifications éditoriales dues aux nouvelles éditions des normes référencées. Cette publication doit être lue conjointement avec la  CEI 60730-1:2010. Elle a été établie sur la base de la troisième édition de cette norme (1999) et de ses Amendement 1 (2003) et Amendement 2 (2007). Les éditions futures de la CEI 60730-1, ou ses amendements, pourront être pris en considération.

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
