1、BRITISH STANDARD BS EN 60503:1998 IEC 60503: 1998 Spools for broadcast videotape recorders (VTRS) The European Standard EN 60503:1998 has the status of a British Standard ICS 33.160.40BSEN60503:1998 This British Standard, having been prepared under the directionof the Electrotechnical Sector Board,
2、was published underthe authority of the Standards Board and comes intoeffect on 15June1998 BSI 04-1999 ISBN 0 580 29930 9 National foreword This British Standard is the English language version of EN 60503:1998. It is identical with IEC60503:1998. It supersedes BS5575:1978 which will be withdrawn on
3、2001-01-01. The UK participation in its preparation was entrusted by Technical Committee EPL/100, Audio, video and multimedia systems and equipment, to Subcommittee EPL/100/3, Equipment and systems in the field of audio, video and audiovisual engineering, which has the responsibility to: aid enquire
4、rs 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 developments and promulgate them in the UK. A list of organizations repr
5、esented on this subcommittee can be obtained on request to its secretary. From 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 othe
6、r, publications may contain identifiers 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 European publications. The British Standards whi

A British Standard does not purport to include a
