7、tional 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) 25200 “Harmonized system of quality assessment for electronic components. Sectional specification: Magnet
8、ic oxide cores for linear transformers”. In 1991 the CENELEC Electronic Components Committee (CECC) accepted CECC 25200:1977 as European Standard EN 125200:1991. As a consequence of implementing the European Standard this British Standard is renumbered as BS EN 125200 and any reference to BS CECC 25
9、200 should be read as a reference to BS EN 125200. This standard is a harmonized specification within the CECC system. Terminology and conventions. The text of the CECC specification has been accepted as suitable for publication, without deviation, as a British Standard. Some terminology and certain
10、 conventions are not identical with those used in British Standards; attention is especially drawn to the following: The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Cross references. The British Stand
11、ard harmonized with CECC 00100 is BS E9000 “General requirements for electronic components of assessed quality harmonized with the CECC system”. For each of the following references to International Standards given in the text, there is a corresponding British Standard; these are as listed below: A
