It is identical with CENELEC Electronic Components Committee (CECC)35000“Harmonized system of quality assessment for electronic
8、 components: Generic specification: travelling wave amplifier tubes”. In 1992 the CENELEC Electronic Components Committee (CECC) accepted CECC35000:1977 as European Standard EN 135000:1992. As a consequence of implementing the European Standard this British Standard is renumbered as BSEN135000 and a
9、ny reference to BS CECC 35000 should be read as a reference to BS EN 135000. This standard gives the terminology, quality assessment procedures and test and measurement procedures applicable to the family of travelling wave amplifier tubes with output power ratings not exceeding500watts. Any blank d
10、etail specification dealing with a particular sub-family of travelling wave amplifier tubes required to be used in conjunction with this standard will select those tests which are considered appropriate to the sub-family and may also give more detailed information relative to the sub-family. This st
11、andard is a harmonized specification within the CECC system. The existing non-harmonized British Standard BS9025 “Travelling wave amplifier tubes of assessed quality: Generic data and methods of test” will eventually be superseded by this standard, but for a period both standards will remain in forc
12、e because of current approvals to BS9025. For the time being, until BS E9000 is published, specifications in the series are subject to the basic rules set down in BS9000 “General requirements for electronic components of assessed quality”. The British Standards Institutions prescribed layout of a de
13、tail specification is given in Part2“Data on generic and detail specifications” of BS9000. Cross references. The British Standard harmonized with CECC00100is BS9000 “General requirements for electronic components of assessed quality”. IEC117substantially agrees in technical content with BS3939 “Grap
