Generic specification: Cathode ray tubes” published by the European Committee for Electrotechnical Standardization (CENELEC). This standard gives the terminology, quality assessment procedures and tes

In 1991 the CENELEC Electronic Components Committee (CECC) accepted CECC 11000:1980 including Amendment 1 and Addendum (1988) as European Standard EN 111000:1991. Any sectional and blank detail specification dealing w
10、ith a particular sub-family of cathode ray tubes required to be used in conjunction with this standard will include those tests that are considered to be appropriate to the sub-family and will also give more detailed information relative to the sub-family. This standard is a harmonized specification
11、 within the CECC system. The existing non-harmonized British Standard BS 9050:1971 “Cathode ray tubes of assessed quality: generic data and methods of test” is now declared obsolescent. Terminology and conventions. The text of the CECC specification has been approved as suitable for publication, wit
12、hout deviation, as a British Standard. Some terminology and certain conventions are used, however, that are not identical with those used in British Standards; attention is especially drawn to the following. The comma has been used throughout as a decimal marker. In British Standards it is current p
13、ractice to use a full point on the baseline as the decimal marker. Cross references The British Standard harmonized with CECC00100 is BSE9000 “General requirements for electronic components of assessed quality harmonized with the CENELEC Electronic Components Committee System” Part 1 “Basic rules”.

35、 Electrotechnical 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 of assessment procedures for the electronic com
36、ponents, and by the grant of an internationally recognized 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 by the CECC, and has been prepared for those co
37、untries taking part in the System who wish to issue national harmonized specifications for CATHODE RAY TUBES. It should be read in conjunction with the current regulations for the CECC System. At the date of printing of this specification, the member countries of the CECC are Austria, Belgium, Denma
38、rk, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the UnitedKingdom. Preface This specification was prepared by CECC WG 11: “ELECTRO-OPTICAL DEVICES”. It is based, wherever possible, on the Publications of the International Electrotechnic
39、al Commission and in particular on IEC 151-14 “Methods of measurement of radar and oscilloscope cathode ray tubes”. The text of this specification was circulated to the CECC for voting in document(s) indicated below and was ratified by the President of the CECC for printing as a CECC Specification.
40、This specification will be supplemented by blank detail specifications applicable to each sub-family of cathode ray tubes. The CECC Management Committee at its meeting in Copenhagen March1979 decided that as the German National Authorized Institution would not be implementing the requirements of thi
41、s CECC generic specification, the text should be published in the English and French versions only.
