19、101:1994 BSI 03-2000 iii Foreword 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 o

20、f the System is to facilitate international 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 accept

21、able in all member countries without further testing. This specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications for FIBRE OPTIC ATTENUATORS TYPE: FIXED. It should be read in conj

22、unction with the current regulations for the CECC System. At the date of printing of this specification, the member countries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, theNetherlands, Norway, Portugal, Spain, Sweden, Switzerland and theUnitedKingdom, and co

It is based, wherever possible, on the Publications of the International Electrotechnical Commission. The text of specification was circulated to the CE

24、CC for voting in the documents listed below and was ratified by the President of the CECC for printing as a CECC specification.

This includes instructions for preparing a DS. 2 Qualification approval 2.1 Procedure The DS shall state the qual

26、ification approval procedure to be used in accordance with 3.3 of CECC80000. 2.2 Test schedule and performance requirements The test schedule for qualification by the fixed sample procedure shall be given in Table 1 of the DS (seeclause4.4). 3 Quality conformance inspection 3.1 Lot-by- lot inspectio

27、n The test schedule for lot-by-lot inspection (groups A and B) shall be given in Table 2 of the DS (seeclause4.4). 3.2 Periodic inspection The test schedule for periodic inspection (groups C and D) shall be given in Table 3 of the DS (seeclause4.4). 4 Preparation of detail specifications (DS) Each B

28、DS is published separately as a pro forma document, with numbered spaces provided for entering the information necessary to create a DS. If the spaces provided are too small, then the information shall be provided on additional sheets forming part of the completed DS. Instructions for filling in the

29、 numbered spaces in a BDS are given below. (1) The name of the ONH under whose authority the DS is published and, if applicable, the organization from whom the DS is available. (2) The CECC symbol and the number allotted to the DS by the CECC General Secretariat. (3) The number and issue number of t

30、he CECC GS; also the national reference(s), if different. (4) If different from the CECC number, the national number of the DS, date of issue and any further information required by the national system, together with any amendment numbers. (5) A brief description of the component or range of compone

(10) Fixed-sample qualification approval test schedule Table 1 shall give the re

37、quired measurements and tests for qualification by fixed-sample procedure. If qualification by lot-by-lot and periodic procedure is specified, insert “NOTAPPLICABLE” in Table 1. If measurements or tests are specified for which no basic procedure is available, or which do not appear in the GS, CECC80
