21、lity. 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 grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System
22、are thereby acceptable in all member countries without further testing. This specification was prepared by CECCWG16“Relays”. The text of the draft based on document CECC (Secretariat)2827 was submitted to the formal vote; together with the voting report, circulated as document CECC(Secretariat)3144,
23、 it was approved by CECC as EN116303 on 10August1992.
