20、ion This specification is a BDS for Fibre Optic Branching Devices of the “Wavelength selective transmissive star” type. This includes instructions for preparing a DS. 2 Qualification approval 2.1 Procedure The DS shall state the qualification approval procedure to be used in accordance with clause 3
21、.3 of EN 181000. 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 (see clauses 2.2, 4.5 and 4.6 of EN 181000). 3 Quality conformance inspection 3.1 Lot-by-lot inspection The test schedule for lot-by-l
22、ot inspection (groups A and B) shall be given in Table 2 of the DS (see clauses 2.2, 4.5 and 4.6 of EN 181000). 3.2 Periodic inspection The test schedule for periodic inspection (groups C and D) shall be given in Table 3 of the DS (see clauses 2.2, 4.5 and 4.6 of EN 181000) 4 Preparation of detail s
23、pecifications (DS) Each BDS is published separately as a pro format 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 Instru
24、ctions 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 the DS is available. 2) The CECC symbol and the number allotted to the DS by the CECC General Secretariat. 3) The number
25、 and issue number of the CEGC 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
26、 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 given in the DS shall be suitable for an entry in CECC 00 200 (Register of Approvals) and CECC 00 300 (Register of Nat
27、ional Documents). 7) An outline drawing with main dimensions which are of importance for interchangeability, and/or reference to the appropriate national or international documents for outlines. Alternatively, this drawing may be given in an annex to the DS, but 7) shall always contain an illustrati
28、on of the general outer appearance of the component. If an existing drawing from an IEC publication, or similar source, is used in a CECC specification, then it can be either first or third angle projection, but the appropriate symbol shall be shown on the drawing: Licensed Copy: sheffieldun sheffie

Alternative outline dimensions or tolerance limits of any variants shal
30、l 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 clause 2.7.1 of EN 181000). Assign a column in the table for each variant
31、 feature. For example, cable type, housing, orientation of ports, means of mounting etc. Instruction: max. values in dB for insertion losses between conduction ports; min. values in dB for return losses; min. values in dB for insertion losses between isolated ports. 9) Supplementary information Ente
32、r the supplementary information with respect to marking of the component, marking and contents of package, ordering information, related documents, certified test records and structural similarity. 10) Fixed sample qualification approval test schedule Table 1 shall give the required measurements and
33、 tests for qualification by fixed-sample procedure. If qualification by lot-by-lot and periodic procedure is specified, insert “NOT APPLICABLE” in Table 1. If measurements or tests are specified for which no basic procedure is available, or which do not appear in the GS EN 181000, each procedure sha
34、ll be clearly diecribed 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) Lot-by-lot inspection test schedule When completed, Table 2 shall give the required measurements and tests for qualification by lot-by-lot proced
35、ure. One or more assessment level(s) shall be given in Table 2. When differing from the preferred levels of the GS (see clause 2.1.5 of EN 181000) the IL and AQL shall be entered and the assessment level(s) titled (X, Y.). If measurements or tests are specified for which no basic procedure is availa
36、ble, or which do not appear in the GS, EN 181000, 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. 12) Periodic C and D testing procedure Table 3 shall give the required measuremen
37、ts and tests for groups C and D periodic tests. One or more assessment level(s) shall be given in Table 3. When differing from the preferred levels of the GS (see clause 2.1.5 of EN 181000) the IL, AQL, p, n, c and t shall be entered and the assessment level(s) titled (X,Y.). 13) Details, measuremen
38、ts, 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 a minimum. Others tests shall be given in the same manner. To fill in the detail of the test the values shall be taken out from the relevant I ETS
