5、 the direction of the Electronic Components Standards Committee. It is identical with IEC Publication384-15-1: “Fixed capacitors for use in electronic equipment. Blank detail specification: Fixed tantalum capacitors with non-solid electrolyte and foil electrode. Assessment level E” published by the

6、International Electrotechnical Commission (IEC). Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards.

7、 Cross-references. The British Standard which implements IEC Publications QC001001:1986 and QC001002:1986 is BS9000: “General requirements for a system for electronic components of assessed quality” Part3:1987 “Specification for national implementation of the IECQ basic rules and rules of procedure”

8、. Scope. This standard lists the ratings, characteristics and inspection requirements which shall be included as mandatory requirements in accordance with BSQC 300200. Detail specification layout. In the event of conflict between the requirements of this specification and the provisions of BS9000 th

9、e latter shall take precedence except that the front page layout will be in accordance with PD9004:1986 “BS9000, CECC and IECQ UK administrative guide.” Circular Letter No.15. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are re

10、sponsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
