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
