2、 This British Standard, having been prepared under the direction of the Electrotechnical Sector Board, was published under the authority of the Standards Board and comes into effect on 15 August 1997 BSI 03-2000 ISBN 0 580 27782 8 National foreword This British Standard is the English language versi
3、on of EN 61315:1997. It is identical with IEC 61315:1995. The UK participation in its preparation was entrusted to Technical Committee EPL/86, Fibre optics, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquirie
4、s 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 committee can be obtained on request to its secretary. From 1 January 1997, all IEC
5、 publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. 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 Attention is drawn to t
6、he fact that Annex ZA 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 “International Stan
