1、BRITISH STANDARD BS EN 60118-12:1997 IEC 60118-12: 1996 Hearing aids Part 12: Dimensions of electrical connector systems The European Standard EN 60118-12:1996 has the status of a British Standard ICS 17.140.50BSEN60118-12:1997 This British Standard, having been prepared under the directionof the El
2、ectrotechnical Sector Board, was published underthe authority of the Standards Board and comes into effect on 15 September 1997 BSI 09-1999 ISBN 0 580 27795 X National foreword This British Standard is the English language version of EN 60118-12:1996. It is identical with IEC 60118-12:1996. It super
3、sedes BS 2813 Specification for dimensions of plugs for hearing aids: 1981 which will be withdrawn on 1997-07-01. The UK participation in its preparation was entrusted to Technical Committee EPL/29, Electroacoustics, which has the responsibility to: aid enquirers to understand the text; present to t
4、he 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 represented on this committee can be obtain
5、ed on request to its secretary. From 1 January 1997, all IEC 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
6、 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 which implement these international or Eur
7、opean 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 Standard does not purport to include all the necessary provisions of a contract.
8、 Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
