7、7-1999 National foreword This British Standard has been prepared under the direction of the Electronic Components Standards Committee. It is identical with CENELEC Electronic Components Committee (CECC)36000 “Harmonized system of quality assessment for electronic components: Generic specification: M
8、agnetrons”. In1992 the CENELEC Electronic Components Committee (CECC) accepted CECC36000:1977 as European Standard EN136000:1992. As a consequence of implementing the European Standard this British Standard is renumbered as BSEN136000and any reference to BSCECC36000should be read as a reference to B
9、SEN136000. This standard gives the terminology, quality assessment procedures and test and measurement procedures applicable to the entire family of magnetrons. Any blank detail specification dealing with a particular sub-family of magnetrons required to be used in conjunction with this standard wil
10、l select those tests which are considered appropriate to the sub-family and may also give more detailed information relative to the sub-family. This standard is a harmonized specification within the CECC system. The existing non-harmonized British Standard BS9030 “Magnetrons of assessed quality: Gen
11、eric data and methods of test” will eventually be superseded by this standard but for a period both standards will remain in force because of current approvals to BS9030. For the time being, until BSE9000 is published, specifications in the series are subject to the basic rules set down in BS9000“Ge
12、neral requirements for electronic components of assessed quality”. The British Standards Institutions prescribed layout of a detail specification is given in Part2 “Data on generic and detail specifications” of BS9000. Cross references. The British Standard harmonized with CECC00100 is BS9000 “Gener
13、al requirements for electronic components of assessed quality”. IEC117 substantially agrees in technical content with BS3939 “Graphical symbols for electrical power, telecommunications and electronics diagrams”. For each of the following references to international standards that is given in the tex
14、t, there is a corresponding British Standard; these are as listed below: Reference to international standard Corresponding British Standard ISO 1000:1973 BS5555:1976 SI units and recommendations for the use of their multiples and of certain other units IEC 27-1:1971 BS 1991 Letter symbols, signs and

CENELEC members are bound to comply with CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard
23、without any alteration. Up-to-date lists and bibliographical references concerning such national 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
24、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 same status as the official versions. CENELEC members are the national electrotechnical committees of Austria Belgium, Denmark, Finland, Fran

27、 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 of the System is to facilitate int
28、ernational trade by the harmonization of the 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 by all member countries withou
29、t 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 issue national harmonized specifications for MAGNETRONS. It should be read in conjunction with document CECC 00100: Basic Rules (1974). At t
30、he date of printing of this document, the member countries of the CECC are Belgium, Denmark, Germany, France, Ireland, Italy, the Netherlands, Norway, Sweden, Switzerland and the UnitedKingdom, and copies of it can be obtained from the National Committees of the CENELEC in these countries. Preface T
31、his generic specification was prepared by CECC Working Group13: “Microwave Tubes”. In accordance with the requirements of document CECC00100 it is based, wherever possible, on the Recommendations of the International Electrotechnical Commission and in particular on IEC Publication235: Measurement of
32、 the electrical properties of microwave tubes. The text of this specification was circulated to the CECC for voting in the documents below and was formally approved by the CECC for printing as a CECC Specification. This specification will be supplemented by blank detail specifications specific to ea
