31、6:2017 IEC 2017 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ PLUGS, SOCKET-OUTLETS AND COUPLERS WITH ARCUATE CONTACTS FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Commi
32、ttees). 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 Availa
33、ble 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 org
34、anizations 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
35、 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 Na
36、tional 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
37、, 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 i
38、tself 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 tha
39、t 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 nat
40、ure 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 reference
41、d 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. Internatio
42、nal Standard IEC 62986 has been prepared by subcommittee 23H: Plugs, socket- outlets and couplers for industrial and similar applications, and for electric vehicles, of IEC technical committee 23: Electrical accessories. The text of this International Standard is based on the following documents: FD
43、IS Report on voting 23H/386/FDIS 23H/387/RVD Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table.

44、n this standard, the following print types are used: requirements: in roman type; conformity statements: in italic type; notes: in small roman type. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/w
45、ebstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 8 IEC 62986:2017 IEC 2017 INTRODUCTION The object of this documen
46、t is to provide for a safe, compact and practical IEC system of standardized plugs and socket-outlets with arcuate contacts. It contains performance and dimensional requirements taking into account essential differences in the infrastructures and installation rules throughout the world. IEC 62986:20
47、17 IEC 2017 9 PLUGS, SOCKET-OUTLETS AND COUPLERS WITH ARCUATE CONTACTS 1 Scope This document sets the general and dimensional interchangeability requirements for plugs, socket-outlets, connectors and appliance inlets with arcuate contacts of standardized configurations (hereinafter referred to as ac
48、cessories), with a rated operating voltage not exceeding 600 V AC at a frequency of 50 Hz and 60 Hz and with rated currents of 20 A and 30 A, primarily intended for commercial use indoors, in conditions where the presence of water is negligible. This document applies to accessories for use when the
49、ambient temperature is normally within the range of 25 C to +40 C. These accessories are intended to be connected to cables of copper or copper alloy only. Interchangeability requirements are defined for IP20 accessories. NOTE The conditions of use indoors are based on the limitations given by IEC 60364-5-51:2005, Table 51A, AD1. Socket-outlets or appliance inlets incorporated in or fixed to electrical equipment are within the sc
