18、s includes instructions for preparing a DS. 2 QUALIFICATION APPROVAL 2. I PROCEDURE The DS shall state the qualification approval procedure to be used in accordance with clause 3.3 of EN 181000. 2.2 TEST SCHEDULE AND PERFORMANCE REQUIREMENTS The test schedule for qualification by the fixed sample pr
19、ocedure shall be given in table 1 of the DS (see clauses 2.2,4.5 and 4.6 of EN 181 000). 3 QUALITY CONFORMANCE INSPECTION 3.7 LOT-BY-LOT INSPECTION The test schedule for lot-by-lot 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 PERIOD
20、IC 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 SPECIFICATIONS (DS) Each BDS is published separately as a pro format document, with numbered spaces provided for entering th
21、e 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 numbered spaces in a BDS are given below: (1) The name of the ONH under whose authonty the DS is
22、 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.

For (5) and (6) the text to be given in the DS shall be suitable for an entry in CECC O0 200 (Register of Approvals) and CECC O0 300 (Register of National Documents). (7) An outline drawing w
25、ith 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 illustration of the general outer appearance of th
26、e 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: st angle projection 3rd angle projection The symbol in the BDS may be conv
27、erted to indicate either Ist or 3rd angle, by deleting the inappropriate part of the drawing. Alternative outline dimensions or tolerance limits of any variants shall be shown, and may be listed in the form of a table alongside the drawing. (8) A list of variants and their identifying features cover
28、ed 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 feature. For example, cable type, housing, orientation of ports, means of mounting etc. Instruction: - max. values in dB for insertio
