4、ection of the Electronic Components Standards Committee. It is identical with CENELEC Electronic Components Committee (CECC) 46001 “Blank detail specification: Cold cathode indicator tubes”. This standard is a harmonized specification within the CECC system. Terminology and conventions The text of t
5、he CECC specification has been accepted as suitable for publication, without deviation, as a British Standard. Certain terminology and conventions are used, however, that are not identical with those used in British Standards. Attention is particularly drawn to the following. The comma has been used
6、 throughout as a decimal marker. In British Standards it is current practice to use a full point (a full stop on the baseline) as the decimal marker. Cross references The British Standard harmonized with CECC 00100 is BS 9000 “General requirements for electronic components of assessed quality”. For
7、each of the following references to other International Standards that are given in the text, there is an equivalent British Standard; these are listed below.

Detail specification layout In the event of conflict between the requirements of this specification and the provisions of Section 3 of BS 9000-2, the latter shall take precedence. In particular the British Standards Institutions prescribed layout for the heading of the deta
9、il specification is given in this section. A British Standard does not purport to include all the necessary provisions of a contract.

15、46001:1977 BSI 10-1999iii Foreword The CENELEC Electronic Components Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object
16、of the System is to facilitate international trade by the harmonization of specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby accepted
17、by all member countries without further testing. This document has been formally approved by the CECC, and has been prepared for those member countries taking part in the System who wish to prepare and issue detail specifications for COLD CATHODE INDICATOR TUBES. It should be read in conjunction wit
18、h document CECC 00100: Basic Rules (1974). At the date of printing of this document, the member countries of the CECC are Belgium, Denmark, Germany, France, Ireland, Italy, Netherlands, Norway, Sweden, Switzerland and the United Kingdom, and copies of it can be obtained from the National Committees
19、of the CENELEC in these countries. Preface This blank detail specification was prepared by CECC Working Group 14: “SPACE-CHARGE CONTROLLED TUBES”. It is one of a series of blank detail specifications for cold cathode indicator tubes, all relating to the generic specification printed as CECC 46000. T
20、he text of this specification was circulated to the CECC for voting in document CECC(Secretariat)427 in September 1975 and was formally approved by the CECC for printing as a CECC Specification.
