Appliance couplers for household and similar general purposes - Part 1: General requirements
This part of lEC 60320 sets the general requirements for appliance couplers for two poles and two poles with earth contact and for the connection of electrical devices for household and similar onto the mains supply. This part of lEC 60320 is also valid for appliance inlets/appliance outlets integrated or incorporated in appliances. The rated voltage does not exceed 250 V (a.c.) and the rated current does not exceed 16 A. Appliance couplers complying with this part of lEC 60320 are suitable for normal use at ambient temperatures not normally exceeding +40 °C, but their average over a period of 24 h does not exceed +35 °C, with a lower limit of the ambient air temperature of -5 °C. Annex E provides test requirements for derating the operating current of an accessory when used in ambient temperatures above +35 °C up to +90 °C. Appliance couplers are not suitable for - use in place of plug and socket-outlet systems according to IEC 60884-1. - use in place of devices for connecting luminaires (DCLs) according to IEC 61995 or 306 luminaire supporting couplers (LSCs). 307 NOTE Requirements for d.c. are under consideration.

Connecteurs pour usages domestiques et usages généraux analogues - Partie 1: Exigences générales
L'IEC 60320-1:2021 établit les exigences générales applicables aux connecteurs bipolaires et bipolaires avec contact de mise à la terre et destinés au raccordement au réseau d'alimentation des dispositifs électriques pour usages domestiques et analogues. Le présent document s'applique également aux socles de connecteurs/socles femelles de connecteurs intégrés ou incorporés dans des appareils d'utilisation. Cette quatrième édition annule et remplace la troisième édition parue en 2015 et l'Amendement 1:2018. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: les tolérances nécessaires ont été ajoutées dans l'ensemble du présent document; l'essai d'échauffement de l'édition 2 a été rétabli en 18.2; l'échauffement a été ajouté à l'Article 21 pour les fiches mobiles mâles; le 23.3 a été réorganisé pour des raisons de lisibilité; l'essai de traction latérale du 23.6 a été mis à jour pour les prises mobiles/fiches mobiles mâles qui comportent des pièces frontales séparées; le 24.1 qui traite de l'essai à la bille a été revu; l'Article 27 qui traite de l'essai au fil incandescent a été mis à jour; l'Annexe C qui traite des séquences d'essais a été revue; l'Annexe E a été ajoutée afin de définir les essais et exigences supplémentaires pour les connecteurs destinés à être utilisés à des températures ambiantes supérieures à +35 °C.

209 FOREWORD
210 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
211 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
212 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
213 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
214 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
215 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
216 in the subject dealt with may participate in this preparatory work. International, governmental and non-
217 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
218 with the International Organization for Standardization (ISO) in accordance with conditions determined by
219 agreement between the two organizations.220 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
221 consensus of opinion on the relevant subjects since each technical committee has representation from all
222 interested IEC National Committees.223 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
224 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
225 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
226 misinterpretation by any end user.227 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
228 transparently to the maximum extent possible in their national and regional publications. Any divergence
229 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
230 the latter.231 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
232 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
233 services carried out by independent certification bodies.234 6) All users should ensure that they have the latest edition of this publication.
235 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
236 members of its technical committees and IEC National Committees for any personal injury, property damage or
237 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees
