18、 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 international trade by the
19、 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 acceptable in all member countries without further testing. Th

This includes instructions for preparing
24、a DS. 2 Qualification approval 2.1 Procedure The DS shall state the qualification approval procedure to be used in accordance with clause3.3 of EN181000. 2.2 Test schedule and performance requirements The test schedule for qualification by the fixed sample procedure shall be given inTable 1 of DS (s
25、eeclauses2.2, 4.5 and4.6 of EN181000). 3 Quality conformance inspection 3.1 Lot-by-lot inspection The test schedule for lot-by-lot inspection (groupsA and B) shall be given inTable 2 of the DS (seeclauses2.2, 4.5 and4.6 of EN 181000). 3.2 Periodic inspection The test schedule for periodic inspection
26、 (groups C and D) shall be given inTable 3 of the DS (seeclauses2.2, 4.5 and4.6 of EN181000). 4 Preparation of Detail Specifications (DS) Each BDS is published separately as a proforma document, with numbered spaces provided for entering the information necessary to create a DS. If the spaces provid
27、ed are too small, then the information shall be provided on additional sheets forming part of the completed DS. Instructions for filling in the 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 th
28、e 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 the 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 info
29、rmation required by the national system, together with any amendment numbers. 5) A brief description of the component or range of components. 6) The level of quality assessment (A, B, C or X), sampling procedure (fixed quantity or lot-by-lot) and the climatic category. For 5) and 6) the text to be g
30、iven in the DS shall be suitable for an entry in CECC00200 (Register of Approvals) and CECC00300 (Register of National Documents). 7) An outline drawing with main dimensions which are of importance for interchangeability, and/or reference to the appropriate national or international document for out
31、lines. Alternatively, this drawing may be given in an annex to the DS, but 7) should always contain an illustration of the general outer appearance of the component.EN181102:1994 4 BSI 04-2000 If an existing drawing from an IEC publication, or similar source, is used in a CECC specification, then it
32、 can be either first or third angle projection, but the appropriate symbol shall be shown on the drawing: The symbol in the BDS may be converted to indicate either1st or3rd angle, by deleting the inappropriate part of the drawing. Alternative outline dimensions or tolerance limits of any variants sh
33、all be shown, and may be listed in the form of a table alongside the drawing. 8) A list of variants and their identifying features covered by the DS. Enter the identification number. “AYY” for each variant of each component (see clause2.7.1 of EN181000). Assign a column in the table for each variant
34、 feature. For example, cable type, housing, orientation of ports, means of mounting etc. Instruction: max. values in dB for insertion losses between conduction ports within each specified operating wavelength range; min. values in dB for return losses, within each specified operating wavelength rang

36、ified test records and structural similarity. 10) Fixed-sample qualification approval test schedule Table 1 shall give the required measurements and tests for qualification by fixed-sample procedure. If qualification by lot-by-lot and periodic procedure is specified, insert “NOT APPLICABLE” inTable
37、1. If measurements or test are specified for which no basic procedure is available, or which do not appear in the GS, EN181000, each procedure shall be clearly described in an individual annex to the DS. The format and the minimum mandatory test sequence shall be the same as specified in the GS. 11)
38、 Lot-by-lot inspection test schedule When completed, Table 2 shall give the required measurements and test for qualification by lot-by-lot procedure. One or more assessment level(s) shall be given inTable 2. When differing from the preferred levels of the GS (see clause2.1.5 of EN181000) the IL and
39、AQL shall be entered and the assessment level(s) titled X, (Y) . . . etc. If measurements or tests are specified for which no basic procedure is available, or which do not appear in the GS, EN181000, each procedure shall be clearly described in an individual annex to the DS. The format and the minim
40、um mandatory test sequence shall be the same as specified in the GS. 12) Periodic C and D testing procedure Table 3 shall give the required measurements and tests for Groups C and D periodic tests. One or more assessment level(s) shall be given inTable 3. When differing from the preferred levels of
41、the GS (seeclause2.1.5 of EN181000) the IL, AQL, p, n, c and t shall be entered and the assessment level(s) titled (X, Y). 13) Details, measurements, and performance requirements Table 4 shall list the details of each tests requirements. It shall be noted that the mandatory tests have been given as
42、a minimum. Other tests shall be given in the same manner. 1st angle projection 3rd angle projectionEN181102:1994 BSI 04-2000 5 Information about manufacturers who have components qualified to this detail specification is available in the current CECC 00200 Register of Approvals.
