3、ittee (CECC) on 20 February 1992. CENELEC members are bound to comply with CENICENELEC Internal Regulations which stipulate lhe conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such natio
4、nal standards may be obtained on application to the General Secretariat of the CECC or to any CENELEC member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its
5、own language and notified to the CECC General Secretariat has the same status as the official versions. CENELEC members are the national electrotechnical commiilees of Austria. Belgium, Denmark, Finland, France. Germany, Greece, Iceland. Ireland. Itaty, Luxembourg, Netherlands. Norway, Portugal, Spa

8、e for Electrotechnical Standardization (CENELEC) whowish 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 compon
9、ents, and by the grant of an internationally recognized 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 CECC WG 20, Opto-Electronic Components and Liquid Cryst
10、al Devices. The text of the draft based on document CECC 20 007 Issue 1 : 1991 was submitted to the formal vote for conversion to a European Standard; together with the voting report, circulated as document CECC(Secretariar)3026 it was approved by CECC as EN 120 007 on 20 February 1992.
