1、BRITISH STANDARD BS EN 160100:1998 Harmonized system of quality assessment for electronic components Sectional specification: Capability approval of manufacturers of printed board assemblies of assessed quality The European Standard EN 160100:1997 has the status of a British Standard ICS 31.180BSEN
2、160100:1998 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 February 1998 BSI 04-1999 ISBN 0 580 29214 2 National foreword This British Standard is the English l
3、anguage version of EN160100:1997 published by the European Electronic Components Committee (CECC) of the European Committee for Electrotechnical Standardization (CENELEC). The UK participation in its preparation was entrusted to Technical Committee EPL/500, Modular electronic units (MEUs), which has
4、 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 developments and promulgate them in t
5、he UK. A list of organizations represented on this committee can be obtained on request to its secretary. 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 E
6、uropean publications. 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 by using the “Find” facility of the BSI Standards Electronic Catalogue. A
7、 British Standard 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

31、nal specification relating to printed board assemblies (as defined in1.3.2 below) of assessed quality which meet the criteria for a modular electronic unit as defined in the generic specification EN160000. It applies to both custom built products and to standard catalogue items and defines the chara
32、cteristics to be assessed and the test methods to be used for capability approval, for quality conformance inspection (lot-by-lot) and maintenance of approval. Acceptance criteria for specific printed board assemblies will be given in the relevant detail specifications in accordance with blank detai
