3、 ii BSI 05-2000 National 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)20004:1987 “Harmonized system of quality assessment for electronic components. Blank deta
4、il specification: Ambient rated photocouplers with phototransistor output”. Terminology and conventions. The text of the CECC specification has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those use
5、d in British Standards; attention is drawn especially to the following. In 1992 the CENELEC Electronics Components Committee (CECC) accepted CECC20004:1987 as European Standard EN120004:1992. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a
6、 full point on the baseline as the decimal marker. Cross-references. The British Standard which implements CECC00100 is BS9000 “General requirements for a system for electronic components of assessed quality” Part2:1983 “Specification for national implementation of CECC basic rules and rules of proc
7、edure”. The Technical Committee has reviewed the provisions of IEC191-2, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard for IEC191-2, published by the International Electrotechnical Commission, is
8、 BS3934“Specification for dimensions of semiconductor devices and integrated electronic circuits”. Scope. This standard lists the ratings, characteristics and inspection requirements which shall be included as mandatory requirements in accordance with BS CECC20000 in any detail specification for the
9、se devices. With respect to Issue1, the most important changes are the additional requirements for photocouplers specified to bridge basic or supplementary insulation or to bridge double or reinforced insulation. Detail specification layout. The front page layout of detail specifications released to
10、 BS CECC family or blank detail specifications will be in accordance with BS9000 Circular Letter No.15. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Stand

The object of the System is to facilitate international trade by the harmonization of the specifications and quality as
21、sessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This European Standard was prepared by CECCWG20, “Opt
