2、0.20BSEN60107-1:1997 This British Standard, having been prepared under the directionof the Electrotechnical Sector Board, was published underthe authority of the Standards Board and comes intoeffect on 15 July 1997 BSI 07-1999 ISBN 0 580 27734 8 National foreword This British Standard is the English

3、 language version of EN60107-1:1997. It is identical with IEC60107-1:1997. It supersedes BS3549-1:1979 which will be withdrawn on1997-12-01. The UK participation in its preparation was entrusted by Technical Committee ELP/100, Audio, video and multimedia systems and equipment, to Subcommittee EPL/10

4、0/1, Receiving equipment, 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 change, and keep the UK interests informed; monitor related international and European de

5、velopments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact thatAnnex ZA lists normative references to international publications with their corresponding European publ

6、ications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standa

7、rd does not purport to include all the necessary provisions of 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. Summary of pages This document comprises a front cover, a
