It is identical with IEC 61300-3-2:1995. The UK participation in its preparation was entrusted by Te
4、chnical 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 to the responsible international/European committee any enquiries on the interpretation, or proposals for c
5、hange, 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 be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 adde

For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both system. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards no
7、rmally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “Internatio
