31、e standard 5.1 General This clause applies to the sampling for inspection and testing before acceptance or rejection of single lots (consignments) when no information about the implementation of quality control or testing during manufacture is available to help in assessing the quality of the lot. I
32、t is also used as the procedure for adjudicating in cases of dispute. Information on the quality verification of nurses woven uniform fabric is given in annex C. 5.2 Sampling 5.2.1 General The following sampling procedure shall be applied (after the lot has been checked for compliance with clause 7)
33、 to determine whether the lot complies with the remaining requirements of the standard, and the sample for inspection so taken shall be deemed to be representative of the lot. SANS 1183:2008 Edition 2.1 7 5.2.2 Sample for inspection From the lot, take at random 30 pieces or all the pieces (whichever
34、 is less) as the sample for inspection. 5.2.3 Laboratory samples for testing From the lot, or from the sample taken in accordance with 5.2.2, take at random five pieces. From each of the five pieces and from a position taken at random, but at least 3 m from an end of the piece, cut a full-width labo
35、ratory sample of area at least 2 m2. 5.3 Compliance The lot shall be deemed to comply with the requirements of the standard if, after inspection and testing of the laboratory samples taken in accordance with 5.2.3, the laboratory samples are found to comply with all the requirements of the standard.
36、 6 Inspection and methods of test 6.1 Inspection 6.1.1 Divide the number of pieces taken in accordance with 5.2.2 into two equal sets. Visually examine the first set for compliance with the requirements given in 4.1, 4.2, 4.3, 4.8 and 4.10. 6.1.2 Measure each piece in the second set for compliance w
37、ith the requirements given in 4.4, 4.5 and 4.6, using SANS 82, SANS 84 and SANS 5091 to measure the width, the length, and the bow and skewness of the weft respectively. 6.2 Conditioning Condition each laboratory sample (see 5.2.3) in accordance with SANS 70 and then cut from each the test specimens

48、instead of concentrating solely on evaluation of the final product, he also direct his attention to the manufacturers quality system. In this connection it should be noted that SANS 9001 covers the provisions of an integrated quality system. Bibliography SANS 9001/ISO 9001, Quality management systems Requirements.
