The object 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 Certif

19、icate, 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 prepared for those countries taking part in the System who wish to prepare and issue national harmon

20、ized detail specifications for CW MAGNETRONS FOR RF HEATING OR COOKING APPLICATIONS. It should be read in conjunction with document CECC00100: Basic Rules (1974). At the date of printing of this document, the member countries of the CECC are Belgium, Denmark, Germany, France, Ireland, Italy, the Net

Preface This blank detail specification was prepared by CECC Working Group13: “Microwave Tubes”. It is one of a series of blank detail specifi

22、cations for magnetrons, all relating to the generic specification printed as CECC36000. 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: Measureme

23、nt of the electrical properties of microwave tubes. The text of this specification was circulated to the CECC for voting in document CECC(Secretariat)479in June1976and was ratified by the CECC for printing as a CECC Specification.
