3、996. 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 to the responsible international/European c
4、ommittee 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 be obtained on request to its secretary. From
5、 1 January 1997, all IEC publications have the number60000 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 identifiers from both systems. Cross-references At
6、tention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement international or European publications referred to in this docume
7、nt 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 a contract. Users of Bri
8、tish Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

22、ing is intended to aid in the preparation of detail specifications. Spaces are provided for entering the information. When the spaces are completed, the detail specification can be drafted in its final form. The spaces are identified by numbers between brackets. Instructions for completing these num
23、bered spaces are given below. When drafting the final detail specification, eliminate the bracketed instruction numbers. 1 The IEC number assigned to the detail specification is added by the National Committee. 2 The date of the detail specification is added by the National Committee. 3 Enter the na
24、me and address of the National Committee. 4 Enter the component classification. 5 Enter the page numbers where the variants are defined. 6 Enter the climatic category, if applicable. 7 Enter the assessment level(s). If the assessment level is other than a standard level, it is designated by the capi
25、tal letter “X”. 8 Add the qualification procedure required for the detail specification (fixed sample or lot-by-lot procedure). 9 Add figures showing the limit dimensions for standard reference components and gauges if they are required. Display the figures in the format shown. 10 Tabulate the ident
