14、1992 BSI 04-2000 2 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 of the
15、System is to facilitate international 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
16、all the 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 issue national harmonized specifications for C.W. POWER AMPLIFIER TRAVELLING WAVE TUBES UP TO500WATTS. It sho
17、uld 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 Netherlands, Norway, Sweden, Switzerland and the UnitedKingdom, and copies of it can be obtain
18、ed from the National Committees of the CENELEC in these countries. Preface This blank detail specification was prepared by CECC Working Group13: “Microwave Tubes”. It is one of a series of blank detail specifications for travelling wave amplifier tubes, all relating to the generic specification prin
19、ted as CECC35000. 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 the electrical properties of microwave tubes. The text of this
20、specification was circulated to the CECC for voting in the documents below and was ratified by the CECC for printing as a CECC Specification.
