17、9202:1994 BSI 01-2000 2 Foreword The CENELEC Electronic Components Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of
18、 the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby accepta
19、ble in all member countries without further testing. This specification was prepared by the German ONH under the Single Originator Procedure for approval and publication of CECC specifications (see RP11-V). The text of the draft based on document CECC(Secretariat)3266/01.93was submitted to the forma
20、l vote; together with the voting report, circulated as document CECC(Secretariat)3387/07.93, it was approved by CECC as EN129202 on9August1993.
