27、 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
28、 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 Commi
29、ttee 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 ac
30、cordance 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
31、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 res
32、ponsible 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 diverge
33、nce 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)
34、 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 damag
35、e 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 publi
36、cation. 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 su
37、ch patent rights. International Standard IEC 60884-2-4 has been prepared by subcommittee 23B: Plugs, socket- outlets and switches, of IEC technical committee 23: Electrical accessories. This third edition cancels and replaces the second edition published in 1999. It constitutes a technical revision.
38、 The main changes from the previous edition are as follows: Clause 7 Classification: deletion of classification according to the degree of protection against harmful ingress of water; inapplicability of 7.1.3 of Part 1 concerning classification according to the provision for earthing: inapplicabilit
39、y of 7.2.2 of Part 1 concerning classification according to the existence of shutters. 60884-2-4 IEC:2007 5 Clause 8 Marking: modification of the symbol for degree of protection to IPXX (Subclause 8.2). Clause 9 Checking of dimensions: addition of compliance paragraph in 9.1. Clause 13 Construction
40、of fixed socket-outlets: applicability of 13.14 of Part 1; addition of requirement about multiple socket-outlets (Subclause 13.101). Clause 14 Construction of plugs and portable socket-outlets: modification of compliance paragraph of 14.23; addition of requirement about minimum nominal cross-section
41、al area of cables for cord extension sets (Subclause 14.101). Clause 16 Resistance to ageing, protection provided by the enclosures, and resistance to humidity: applicability of the whole Clause of Part 1. Clause 21 Normal operation: addition of maximum specified dimensions, including tolerance, of
42、the test plug. Figures: new figures for gauges for the verification of maximum and minimum withdrawal force. Annexes: deletion of informative Annex AA and inclusion of the relevant information in normative Annex B. The text of this standard is based on the following documents: CDV Report on voting 2
43、3B/836/CDV 23B/858/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This Part 2-4 is intended to be used in conjunction with IEC
44、 60884-1 and IEC 60906-3. It was established on the basis of the third edition of IEC 60884-1 (2002) and of its Amendment 1 (2006). This Part 2-4 supplements or modifies the corresponding clauses in IEC 60884-1, so as to convert that publication into the IEC standard: Particular requirements for plu
45、gs and socket- outlets for SELV. When a particular subclause of Part 1 is mentioned in this Part 2-4, that subclause applies as far as reasonable. Where this standard states “addition”, “modification” or “replacement”, the relevant text of Part 1 is to be adapted accordingly. 6 60884-2-4 IEC:2007 In
46、 this standard the following print types are used: requirements proper: in roman type; test specification: in italic type; explanatory notes: in small roman type. Subclauses or figures which are additional to those in Part 1 are numbered starting from 101; supplementary annexes are entitled AA, BB,
47、etc. When clauses of Part 1 are declared as applicable, they apply only where they contain requirements concerning plugs and socket-outlets for SELV. A list of all parts of the IEC 60884 series, under the general title: Plugs and socket-outlets for household and similar purposes, can be found on the
48、 IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdr
49、awn, replaced by a revised edition, or amended. 60884-2-4 IEC:2007 7 PLUGS AND SOCKET-OUTLETS FOR HOUSEHOLD AND SIMILAR PURPOSES Part 2-4: Particular requirements for plugs and socket-outlets for SELV 1 Scope Replacement: This Part 2-4 of IEC 60884 applies to plugs, fixed or portable socket-outlets, and to socket- outlets for appliances from 6 V up to and includi
