1、BRITISH STANDARD AEROSPACE SERIES BS EN 2591-316:1998 Elements of electrical and optical connection Testmethods Part 316: Ozone resistance The European Standard EN2591-316:1997 has the status of a British Standard ICS 49.060BS EN2591-316:1998 This British Standard, having been prepared under the dir
2、ection of the Engineering Sector Board, was published under the authority of the Standards Board and comes intoeffect on 15 January 1998 BSI 05-1999 ISBN 0 580 29478 1 National foreword This British Standard is the English language version of EN2591-316:1997. The UK participation in its preparation
3、was entrusted by Technical Committee ACE/6, Aerospace avionic, electrical and fibre optic technology, to Subcommittee ACE/6/3, Aerospace connectors, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the
4、 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. Cross-references Attention is dra
