17、nts of assessed quality. The object of the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the granting of an internationally recognized Mark, or Certificate, of Conformity. The components prod

18、uced under the System are thereby acceptable in all member countries without further testing. This specification was prepared by CECC WG16 Relays.
