45、 B Notes to purchasers (This appendix does not form part of the requirements of the specification) The following requirements must be specified in tender invitations and in each order or contract: a) the type (see 3.2); b) the fibre composition (see 3.3); c) the size(s) required (see 3.4.1); d) the
46、colour and, when relevant, the colour(s) of stripes incorporated in the rib top (see 3.6); e) the method of toe closure (see 3.7); f) additional marking, if required (see 4.3.3). SANS 1118-9:2008 Edition 1.3 10 Appendix C Quality evaluation of knee-high stockings and ankle socks (This appendix does
47、not form part of the requirements of the specification) C.1 Quality verification C.1.1 When a purchaser requires ongoing verification of the quality of knee-high stockings and ankle socks, it is suggested that, instead of concentrating solely on evaluation of the final product, he also direct his at
48、tention to the manufacturers quality system. In this connection it should be noted that SANS 9001 covers the provision of an integrated quality system. Amdt 2 C.1.2 If the knee-high stockings or ankle socks do not bear the certification mark and no information about the implementation of quality con
49、trol or testing during manufacture is available to help in assessing the quality of a lot, and a purchaser wishes to establish by inspection and testing of samples of the final product whether a lot (as defined in C.2.1) of the knee-high stockings or ankle socks complies with this part of SANS 1118, the sampling plan given in C.2 can be applied.
