CENELEC members are bound to comply with
11、the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the General Secretariat

16、sh 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 recognize
17、d Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This European Standard was prepared by CECCWG22, “RF Connectors”. The text of the draft based on document CECC22110 Issue 1:1982 (with A1 to A3) was
18、 submitted to the formal vote for conversion to a European Standard; together with the voting report, circulated as document CECC(Secretariat)3338 it was approved by CECCas EN122110 on7May1993.
