3、8:1997. It is identical with IEC 61300-2-8:1995. The UK participation in its preparation was entrusted by Technical Committee EPL/86, Fibre optics, to Subcommittee EPL/86/2, Interconnecting devices and passive components, which has the responsibility to: aid enquirers to understand the text; present
4、 to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can b
5、e obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the other, publications may contain ident
6、ifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding or European publications. The BritishStandards which implement these internationa
7、l or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of
8、a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

21、o repetitive shocks. It simulates repetitive shocks likely to be encountered by the devices during normal service. 1.2 General description This procedure is conducted in accordance with IEC68-2-29, test Eb. The specimen is fastened to the table of a bump tester and is subjected to repeated half-sine
22、 pulses. 1.3 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this part of IEC1300. At the time of publication, the edition indicated was valid. All normative documents are subject to revision, and parties to agr
