19、omposed 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 the System is to facilitate international trade by the harmonization of the specificati
20、ons and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Confomity, The components produced under the System are thereby acceptable in all member countries without further testing. This specification was prepared by t
21、he German ONH under the Single Originator Procedure for approval and publication of CECC specifications (see RP 11 Part V). The text of the draft based on document CECC (Secretaria1)3263/01.93 was submitted to the formal vote; together with the voting report, circulated as document CECC(Secretariat)
22、33847.93, it was approved by CECC as EN 129 102 on 9 August 1993. The following dates were fixed: - latest date of announcement of the (doa) EN at national level - latest date of publication of an identical national standard - latest date of withdrawal of conflicting national standards 1 993-1 1-08
