6、) shall be given in table 2 of the DS (see clauses 2.2, 4.5 and 4.6 of EN 181 000). 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 181 000). PREPARATION OF DETAIL SPECIFICATIONS (DS) Each BDS is p

7、ublished separately as a pro forma document, with numbered spaces provided for entering the informa- tion 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 numb

8、ered 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.

(7) An outline drawing with main dimensions which are of importance for interchangeability, and/or reference to the appropriate national or international document for outlines. Alternatively, this drawing may be given in an annex to the DS, but (7) shall a

12、lways contain an illustration of the general outer appearance of the component. If an existing drawing from an IEC publication, or simi- lar source, is used in a CECC specification, then it can be either first or third angle projection, but the appro- priate symbol shall be shown on the drawing: Ist

13、 angle projection 3rd angle projection The symbol in the BDS may be converted to indicate either 1st or 3rd angle, by deleting the inappropriate part of the drawing.

(9) Supplementary information Enter the s

16、upplementary 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 tests

17、 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 181 000, each procedure shall b

18、e 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) Lot-by-lot inspection test schedule When completed, table 2 shall give the required measurements and tests for qualification by lot-by- lot procedur

19、e. One or more assessment level(s) shall be given in table 2. When differing from the prefer- red 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) . etc. If measurements or tests are specified for which no basic procedure is a

20、vailable, or which do not appear in the GS, EN 181 000, 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 mea
