13、zation 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 Interna
14、tional 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 i
15、n 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 th
16、e 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 hav
17、e 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 misi
18、nterpretation 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 natio
19、nal 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 c
20、arried 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
21、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 dra
22、wn 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
23、 be held responsible for identifying any or all such patent rights. This fourth edition of IEC Guide 112 has been prepared in accordance with ISO/IEC Directives, Part 1, Annex A, by the IEC Advisory Committee on Safety (ACOS). This is a non-mandatory guide in accordance with SMB Decision 136/8. This
24、 fourth edition cancels and replaces the third edition published in 2008. This edition constitutes a technical revision. This new edition includes the following significant technical changes with respect to the previous edition: it makes reference to the latest editions of IEC 60065 and IEC 60950-1;
25、 it deals additionally with equipment containing coin / button cell batteries. 4 IEC GUIDE 112:2017 IEC 2017 The text of this IEC Guide is based on the following documents: Approval document Report on voting C/2004/DV C/2025/RV Full information on the voting for the approval of this International St
26、andard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A bilingual version of this publication may be issued at a later date. IEC GUIDE 112:2017 IEC 2017 5 INTRODUCTION This Guide contains guidelines
27、 for using the current editions of IEC 60065 and IEC 60950-1 in evaluating the safety of multimedia equipment. The following fundamental principle was adopted as the basis for this Guide: Equipment complying with the requirements of IEC 60065, as well as equipment complying with the requirements of
28、IEC 60950-1, is considered to be safe when used on its own. Such equipment when interconnected in multimedia systems in accordance with the installation instructions is also considered to be safe. It should be noted that there are a number of differences between the two standards. Requirements which
29、 should be fulfilled in addition to those in the current two standards are specified in this Guide. Additional clarifications are under consideration for both publications in TC 108. Whenever IEC 60065 or IEC 60950-1 are amended or revised, or technical or market conditions change significantly, ACO
30、S will consider this Guide for revision. In addition, it should be noted that IEC 62368-1 may be used as an alternative to either IEC 60065 or IEC 60950-1. For a multimedia system containing Class I and Class II equipment, the connection to the supply should ensure a reliable connection to protectiv
31、e earth for Class I equipment. 6 IEC GUIDE 112:2017 IEC 2017 GUIDE ON THE SAFETY OF MULTIMEDIA EQUIPMENT 1 Scope This Guide contains guidelines for using the current editions of IEC 60065 and IEC 60950-1 in evaluating the safety of multimedia equipment. This Guide focuses on the use of IEC 60065 or
32、IEC 60950-1. As an alternative to both standards, IEC 62368-1 may be used. 2 Reference publications IEC 60065:2014, Audio, video and similar electronic apparatus Safety requirements IEC 60950-1:2005, Information technology equipment Safety Part 1: General requirements IEC 60950-1:2005/AMD1:2009 IEC
33、60950-1:2005/AMD2:2013 IEC 62368-1, Audio/video, information and communication technology equipment Part 1: Safety requirements 3 Guidelines 3.1 Compliance Equipment for use in multimedia systems should comply with: IEC 60065 or IEC 60950-1, according to the manufacturers choice; and the additions l
34、isted in Clause 3. As explained in Clause 1, this Guide focuses on the use of IEC 60065 or IEC 60950-1. Alternatively, IEC 62368-1 may be considered. 3.2 General requirements IEC 60065:2014, Clause 3: this clause is applicable. IEC 60950-1:2005, 1.3: no additions required. 3.3 Marking IEC 60065:2014
35、, Clause 5: this clause is applicable together with the following addition to 5.5: For equipment covered by IEC 60065 intended for use in multimedia systems, the instructions for use and installation should give the necessary information to ensure correct and safe installation and interconnection of
36、 the equipment. IEC 60950-1:2005, IEC 60950-1:2005/AMD1:2009 and IEC 60950-1:2005/AMD2:2013, 1.7: no additions required. IEC GUIDE 112:2017 IEC 2017 7 3.4 Interfaces to the telecommunication network IEC 60065: Annex B of IEC 60065:2014 should be applied to equipment to which IEC 60065 is applied and
37、 which is intended for use in multimedia systems and for connection to a telecommunication network. Alternatively, Clause 6 of IEC 60950-1:2005, IEC 60950-1:2005/AMD1:2009 and IEC 60950-1:2005/AMD2:2013 may be applied. NOTE 1 This choice applies to this item only and is permitted due to the fast evo
38、lution of the technology. NOTE 2 For telecommunications networks in Australia, due to existing national differences to both standards, only Clause 6 of AS/NZS 60950-1:2015 may be applied to IEC 60065 equipment. Annex B of IEC 60065:2014 is not applicable in Australia. 3.5 Equipment containing coin/b
39、utton cell batteries Subclauses 2.7.15 (definition), 5.4 c) (marking), 5.5.2 j) (instructions), and 12.7 (requirements) of IEC 60065:2014 should be applied to equipment with user replaceable coin/button cell batteries when IEC 60950-1 is applied. NOTE The publication of IEC 60065:2014/COR2:2016 makes the requirements also valid for lithium batteries. _ INTERNATIONAL ELECTROTECHNICAL COMMISSION 3, rue de Varemb PO Box 131 CH-1211 Geneva 20 Switzerland Tel: + 41 22 919 02 11 Fax: + 41 22 919 03 00 infoiec.ch www.iec.ch
