15、 CENELEC members Ref. No. EN 147101:1994 EEN147101:1994 BSI 04-2000 2 Foreword The CENELEC Electronic Components 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
16、 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 components
17、 produced under the System are thereby acceptable in all member countries without further testing. This specification was prepared by CECC WG16 “Relays”. The text of the draft based on document CECC (Secretariat)2782 was submitted to the formal vote; together with the voting report, circulated as do
18、cument CECC(Secretariat)3142, it was approved by CECC as EN147101 on10August1992.

30、ualification approval procedures In accordance with CECC00114/II 1.4method1 (fixed sampling). Sampling and test schedule are described inTable 2. The tests specified and their order are mandatory. Additional samples are prescribed in some sampling groups to allow replacement of defective samples in
31、the sampling groups. After the use of these sockets, no complementary replacement is allowed. 4 Quality conformance inspection Quality conformance inspection contains the tests stated inTable 1: Group A and B tests for inspection lot acceptance. Group C periodic tests. Unless otherwise stated in thi
32、s specification, all tests ofTable 1 are mandatory. Where a sub-group contains cumulative tests, the order of the tests is mandatory. Specimens subjected to tests denoted as destructive (D) shall not be released for delivery. 4.1 Formation of inspection lots According to CECC00114/II clause3.1. 4.2
