19、ectronic components 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 grant of an internationally recognized Mark, or Certificate, of Conformity. The co

20、mponents produced under the System are thereby acceptable in all member countries without further testing. This specification was prepared by CECC WG12 “Magnetic components: Magnetic wound components”. The text of the draft based on document CECC (Secretariat)2865 was submitted to the formal vote; t

21、ogether with the voting report, circulated as document CECC (Secretariat)3058, it was approved by CECC as EN129101 on23 April1992.
