14、ntries of the European Committee for Electronical 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 harmonization of the specifications and quality assessment proc

15、edures for electronic components and by the grant of an internationally recognised Mark, or Certificate, of Conformity. The components produced under the System are thereby accepted by all member countries without further testing. This document has been formally approved by the CECC, and has been pr

16、epared for those member countries taking part in the System who wish to issue national harmonized specifications for IMAGE CONVERTER AND IMAGE INTENSIFIER TUBES. It should be read in conjunction with document CECC00100: Basic Rules (1974). Preface This blank detail specification was proposed by CECC

17、 Working Group11: “ELECTRO-OPTICAL DEVICES”. It is a blank detail specification for image converter and image intensifier tubes relating to the generic specification printed as CECC12000. The text of this specification was circulated to the CECC, for voting, in document CECC(Secretariat)381in July19

18、75, and following ratification of the Report on the Voting in CECC(Secretariat)555in December1976 was approved by the CECC Management Committee for printing as a CECC Specification. It is recognised that the layout proposed cannot be applied to all detail specifications based on this document. The C

19、ECC Management Committee at its meeting in Copenhagen in March1979 decided that as the German National Authorized Institution would not be implementing the requirements of this CECC generic specification, the text should be published in the English and French versions only.
