21、zation 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 and in addition to other activities, I

22、EC 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 Committee interested in the subject dealt wi

23、th 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 accordance with conditions determined by a

24、greement 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 interested IEC National Committees. 3) I

25、EC 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 responsible for the way in which they are u

26、sed 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 divergence between any IEC Publication and the

27、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 marks of conformity. IEC is not responsible

28、 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 experts and members of its technical committee

29、s 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 Publication or any other IEC Publications.

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 ri

31、ghts. IEC shall not be held responsible for identifying any or all such patent rights.

36、ety 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 manufacturing

37、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 assessment scheme.

38、 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 (including any amen

39、dments) 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 and definit

40、ions 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 4 Conforman

41、ce 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 appropriate way t

42、o make the connections necessary to perform the relevant test. BS EN 62911:2016 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

43、 contact 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

44、earth 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 overc

45、urrent 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 volta

46、ge drop, 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 measur

47、ing probe and the conductive part under test does not influence the test result. 5.2 Electric strength test Routine tests for electric strength shall be carried out between circuits connected to the mains (primary circuits) and accessible conductive parts. For accessible circuits not connected to th

48、e mains (secondary circuits), it is permitted to test separately, before final assembly, subassemblies and components, such as transformers, if the relevant insulation cannot be tested in the complete equipment, provided that the complete equipment complies with IEC 60065, IEC 60950-1 or IEC 62368-1

49、 as appropriate. The insulation of the equipment shall be checked by the following test: for equipment supplied by an a.c. mains, an a.c. test voltage of substantially sine-wave form, having mains frequency, or a d.c. test voltage or a combination of both with a peak value as specified in Table 1 is applied; for equipment supplied by a d.c. mains, a d.c. voltage according to Table 2 is applied; for equipment supplied by either an a.c. mains or a d.c. mains, th
