24、ical 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
25、 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 C
26、ommittee 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) i
27、n 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
28、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
29、 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 div
30、ergence 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
31、 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 ex
32、perts 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
33、 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
34、 Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62911 has been prepared by TC108: Safety of electronic equipment within the field of audio/video, information technology and communication tec
35、hnology The text of this standard is based on the following documents: FDIS Report on voting 108/616/FDIS 108/635/RVD 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 wi
36、th the ISO/IEC Directives, Part 2. In this standard, the following print types or formats are used: requirements proper and normative annexes: in roman type; 4 IEC 62911:2016 IEC 2016 compliance statements and test specifications: in italic type; notes/explanatory matter: in smaller roman type; norm
37、ative conditions within tables: in smaller roman type; terms that are defined in Clause 3: bold. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specif
38、ic publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 62911:2016 IEC 2016 5 AUDIO, VIDEO AND INFORMATION TECHNOLOGY EQUIPMENT ROUTINE ELECTRICAL SAFETY TESTING IN PRODUCTION 1 Scope This International Standard defines routine ele
39、ctrical safety test procedures for use during or after manufacturing of complete equipment, sub-assemblies or components, complying with IEC 60065, IEC 60950-1 or IEC 62368-1 and powered by an a.c. mains supply or d.c. mains supply, to detect manufacturing failures and unacceptable tolerances in man
40、ufacturing and materials. NOTE All the tests defined in this standard do not necessarily have to be performed at the end product manufacturing location. The optimal location for the routine electrical safety tests can be defined by the equipment manufacturer and reviewed under the conformity assessm
41、ent scheme. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includi
42、ng any amendments) applies. IEC 60065, Audio, video and similar electronic apparatus Safety requirements IEC 60950-1, Information technology equipment Safety Part 1: General requirements IEC 62368-1, Audio/video, information and communication technology equipment Part 1: Safety requirements 3 Terms
43、and definitions For the purposes of this document, the terms and definitions given in IEC 60065, IEC 60950-1 and IEC 62368-1, as well as the following apply. 3.1 routine electrical safety test electrical safety test to which each individual equipment is subjected during or at the end of manufacture
44、4 Conformance Equipment shall pass the routine electrical safety tests of Clause 5 where applicable and the results of these tests shall be recorded according to Clause 6 prior to shipment from the manufacturing site. NOTE Practical measures can be used to conduct the test, such as finding an approp
45、riate way to make the connections necessary to perform the relevant test. 6 IEC 62911:2016 IEC 2016 5 Routine electrical safety tests 5.1 Resistance of protective bonding system For class I equipment, the continuity of the protective bonding system shall be checked between the protective earth conta
46、ct of the mains plug or appliance inlet, or the protective earthing terminal in case of a permanently connected equipment, and the accessible conductive parts that need to be connected to the protective earthing terminal for compliance with the requirements of the standard, and the protective earth
47、contact of the socket-outlets respectively, if provided to deliver mains power to other equipment. NOTE 1 Functional earth is not considered a part of the protective bonding system and as a consequence, it does not need to be tested. The minimum test current is 150 % of the rating of the overcurrent
48、 device protecting the protective bonding conductor (the protective current rating), but not less than 10 A and not more than 25 A (a.c. or d.c.), applied for any duration between 1 s and 4 s. The source shall have a no-load voltage not exceeding 12 V. The resistance, calculated from the voltage dro
49、p, shall not exceed 0,1 . It is permitted to include the power cord (if any) in the resistance measurement and, if the result exceeds 0,1 , to subtract the resistance of the protective earthing conductor of the power cord. NOTE 2 Ensure that the contact resistance between the tip of the measuring probe and the conductive part under test does not influence the test result. 5.2 Electric strength test
