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

IEC 60730-2-7:2015(E) 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 standard is also applicable to individual timers utilized as part of a control system or timers which are mechanically integral with multifunctional controls having non-electrical outputs. This standard does not apply to time-delay switches (TDS) within the scope of IEC 60669-2-3. This standard applies to the inherent safety, to the operating characteristics where such are associated with equipment protection and to the testing of timers used in appliances and other apparatus, electrical and non-electrical, for household and similar purposes, but also extended to industrial purposes when no dedicated product standards exist, such as that for central heating, air conditioning, process heating, etc. Timers 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. This third edition cancels and replaces the second edition published in 2008. This third edition constitutes a technical revision. This new edition revises the compliance criteria of type 1.S and 2.S action, revises the requirements for filament lamp loads, adds requirements for abnormal operation in Annex H, removes some special requirements for single countries as well as updates the standard to IEC 60730-1:2010, fourth edition. Key words: Timers, Time Switches

Automatische elektrische Regel- und Steuergeräte - Teil 2-7: Besondere Anforderungen an Zeitsteuergeräte und Schaltuhren

Dispositifs de commande électrique automatiques - Partie 2-7: Règles particulières pour les minuteries et les minuteries cycliques

IEC 60730-2-7:2015 s'applique aux minuteries et aux minuteries cycliques qui peuvent utiliser l'électricité, le gaz, le pétrole, un combustible solide, l'énergie thermique solaire, etc., ou une combinaison de ces énergies, y compris des applications de chauffage, de climatisation et analogues. La présente norme s'applique également aux minuteries particulières qui sont utilisées en tant que parties d'un système de commande ou aux minuteries qui sont intégrées mécaniquement dans des dispositifs de commande multifonctions qui possèdent des sorties non électriques. La présente norme ne s'applique pas aux interrupteurs temporisés (Time-Delay Switches – TDS) qui relèvent du domaine d'application de l’IEC 60669-2-3. La présente norme s'applique à la sécurité intrinsèque, aux caractéristiques de fonctionnement dans la mesure où elles interviennent dans la protection des matériels ainsi qu'aux essais des minuteries utilisées dans les appareils et autres appareillages, électriques et non électriques, à usage domestique et analogue, mais aussi avec une extension aux applications industrielles pour lesquelles il n'existe aucune norme de produit spécifique, telles que celles pour le chauffage central, la climatisation, la production de chaleur industrielle, etc. Les minuteries pour les matériels qui ne sont pas prévus pour un usage domestique normal, mais qui peuvent néanmoins être utilisés par le grand public, comme les matériels prévus pour être utilisés par des profanes dans les magasins, dans l'industrie légère et dans les fermes, entrent dans le domaine d'application de la présente norme. Cette troisième édition annule et remplace la deuxième édition parue en 2008. Cette troisième édition constitue une révision technique. La présente nouvelle édition révise les critères de conformité des actions de type 1.S et 2.S ainsi que les exigences pour les charges par lampes à filament, elle ajoute des exigences pour le fonctionnement anormal dans l'Annexe H, elle supprime une partie des exigences spécifiques à certains pays et elle met la norme à jour par rapport à l'IEC 60730-1:2010, quatrième édition. Mots clés: minuteries, minuteries cycliques La présente partie 2-7 est destinée à être utilisée conjointement avec l'IEC 60730-1:2013.

AUTOMATIC ELECTRICAL CONTROLS –

Part 2-7: Particular requirements
for timers and time switches
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.
