24、ents Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is to facilitate international trade by the harmon

The components produced under the System are thereby acceptable in all member countries without further testing. This Euro
