22、 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 harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally re
23、cognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to is
24、sue national harmonized specifications for electromechanical all-or-nothing relays. It should be read in conjunction with the current regulations for the CECC system. Foreword This specification was prepared by CECC WG 16 “Relays”. It is based, wherever possible, on the publications of the Internati
25、onal Electrotechnical Commission (IEC). The CECC voting procedure has been concluded on draft prEN 116500 circulated as document CECC (Secretariat) 2777/4.91 and has resulted in a positive vote. The voting report document CECC (Secretariat) 3009/1.92 has been submitted for formal approval and has be

Scope This sectional specification applies to electromechanical all-or-nothing telecom relays of assessed qualit
30、y. Relays according to this standard are provided for the operation in telecommunication applications. However, as electromechanical all-or-nothing relays they are suitable also for particular industrial and other applications. It selects from the generic specification EN 116000-1:1992 (CECC 16000-I
31、:1990) and other sources the appropriate methods of tests to be used in detail specifications derived from this specification, and contains basic test schedules to be used in the preparation of such specifications. Detailed test schedules are contained in the blank detail specifications supplementar
