The text of this standard consists of the text of CECC14001 Issue11984 of the corresponding CECC Specification. CENELEC members are bound to comply
9、 with 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 Secretari

A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the CECC General Secretariat has the
11、same status as the official versions. CENELEC members are the national electrotechnical committees of Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and United Kingdom.

14、ho 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 andquality assessment procedures for electronic components, and by the grant of an internationally recog
15、nized Mark, or Certificate, of Conformity. The components produced under the System are thereby accepted by all member countries without further testing. This specification has been formally approved bytheCECC, and has been prepared for those countries taking part in the System who wish toissue nati
16、onal harmonized specifications for PHOTOMULTIPLIER TUBES. It should be read inconjunction with document CECC00100: BasicRules (1974). At the date of printing of this document the membercountries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Nor

It is a blank detail specification for photomultiplier tubes relating to the generic specification CECC14000. The text of this spe
18、cification was circulated to the CECC for voting in the document indicated below and was ratified by the President of the CECC for printing as a CECC Specification: It is recognized that the layout proposed cannot be applied to all detail specifications based on this document. The CECC Management Co
19、mmittee at its meeting in Copenhagen in March1979 decided that as the German National Authorized Institution would not be implementing the requirements of this CECC specification, the text should be published in the English and French versions only.
