14、rmonized System for electronic 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,
15、 of Conformity. The components produced under the System are thereby accepted by all member countries without further testing. This blank detail specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmon

It should be read in conjunction with the current regulations for the CECC System. Preface This blank detail specification was prepared by CECC Working Group3: “Capacitors”, and it is a
17、n editorially revised version of CECC30401Issue1. It is one of a series of blank detail specifications all relating to the sectional specification CECC30400, Issue2.
