6、reword This British Standard has been prepared under the direction of the Electronic Components Standards Committee. It is identical with CENELEC Electronic Components Committee (CECC) 25400:1982 “Harmonized system of quality assessment for electronic components: Sectional specification: Adjusters u
7、sed with magnetic oxide cores for use in inductors and tuned transformers”. In 1991 the CENELEC Electronic Components Committee (CECC) accepted CECC 25400:1982 as European Standard EN 125400:1991. As a consequence of implementing the European Standard this British Standard is renumbered as BS EN 125
8、400 and any reference to BS CECC 25400 should be read as a reference to BS EN 125400. This standard is a harmonized specification within the CECC system. Terminology and conventions. The text of the CECC specification has been approved as suitable for publication as a British Standard without deviat
