9、al 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) 25100 “Harmonized system of quality assessment for electronic components. Sectional specification: Magnetic ox
10、ide cores for inductor applications”. In 1991 the CENELEC Electronic Components Committee (CECC) accepted CECC 25100:1976 as European Standard EN 125100:1991. As a consequence of implementing the European Standard this British Standard is renumbered as BS EN 125100 and any reference to BS CECC 25100
11、 should be read as a reference to BS EN 125100. This standard is a harmonized specification within the CECC system. The existing non-harmonized British Standard, BS 9631:1974 “Rules for the preparation of detail specifications for ferrite cores of assessed quality for use in inductors-Full assessmen
12、t”, will eventually be superseded by this standard, but for a period both standards will remain in force because of current approvals to BS 9631. Terminology and conventions. The text of the CECC specification has been accepted as suitable for publication, without deviation, as a British Standard. C
13、ertain terminology and conventions are used, however, that are not identical with those used in British Standards. Attention is particularly 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 (a full stop on the baseli
14、ne) as the decimal marker. Cross references. The British Standard harmonized with CECC 00100 is BS 9000 “General requirements for electronic components of assessed quality”. For each of the following references to other International Standards that are given in the text, there is an equivalent Briti
15、sh Standard; these are listed below.

17、 cores for telecommunication NOTEThere are as yet no equivalent British Standards for IEC 205, IEC 367, IEC 424.
