5、2006, Uncontrolled Copy, (c) BSI BS CECC 31201:1981 ii BSI 09-1999 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 31201: “Blank detail specification: Fix
6、ed capacitors with metallized electrodes and polypropylene dielectric”. 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 deviation. Some term
7、inology and certain conventions are not identical with those used in British Standards. Attention is especially drawn to the following. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Cross
8、 references The British Standard harmonized with CECC 00100 is BS E9000 “Specification for general requirements for electronic components of assessed quality harmonized with the CENELEC Electronic Components Committee System, Part 1 Basic rules”. Scope This standard lists the ratings, characteristic
9、s and inspection requirements which shall be included as mandatory requirements in accordance with BS CECC 31200. Detail specification layout In the event of conflict between the requirements of this specification and the provisions of BS E9000 the latter shall take precedence except that the front
10、page layout will be in accordance with BS 9000 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 Standard does not of itself confer imm
11、unity from legal obligations.

15、rd The CENELEC Electronic Components Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is to facilitate i
16、nternational trade by the harmonization of the specifications and quality assessment 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 accepted by all member countries with
17、out further testing. This blank detail specification has been formally approved by the CECC and has been prepared for those member countries taking part in the System who wish to issue national harmonized specifications for FIXED CAPACITORS WITH METALLIZED ELECTRODES AND POLYPROPYLENE DIELECTRIC. It
18、 should be read in conjunction with document CECC 00100: Basic Rules (1974). At the date of printing of this document the member countries of the CECC are Belgium, Denmark, France, Germany, Ireland, Italy, the Netherlands, Norway, Sweden, Switzerland and the United Kingdom. Copies of it can be obtai
19、ned from the addressees shown on the inside cover. Preface This blank detail specification was prepared by CECC Working Group 3: Capacitors. It is one of a series of blank detail specifications all relating to the sectional specification CECC 31200. In accordance with the requirements of document CE
20、CC 00100 it is based, wherever possible, on the Publications of the International Electrotechnical Commission. As there are more than nine sectional specifications related to CECC 30000: generic specification, Fixed Capacitors, the CECC Management Committee decided that these extra specifications sh
21、ould be numbered in the series 31100, 31200, 31300 etc. . . . . There is no generic specification numbered 31000. The text of this blank detail specification was circulated to the CECC for voting in the documents listed below and was ratified by the CECC Management Committee for printing as a CECC S
