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. La présente Partie 2-9 doit être utilisée conjointement avec la CEI 60730-1. 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.

non-bimetallic single operation device

single operation device having a temperature sensing element which is part of a combination action

control, the operation of which cannot be separated from other functions of the control and having a

non-bimetallic thermal element that operates only once and then requires complete or partial

replacement

NOTE 1 When such parts can be tested separately, they are considered to be thermal links within the scope of EN 60691.

NOTE 2 The ageing period and thermal response of the device is dependent on the intended use of the device. As a result,

the nature of the testing applicable to the device should be representative of the application conditions for which the protective

control is intended (see 7.2).

NOTE 3 Non-bimetallic single operation devices provide the equivalent of micro-disconnection.

for temperature sensing controls
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.

International Standard IEC 60730-2-9 has been prepared by IEC technical committee 72:

Automatic controls for household use.

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.
