32、ample for compliance with the requirements of clause 7, inspect all the pantihose or knee-highs in the sample for compliance with the requirements given in 5.1, 5.2, 5.3 and 5.4.1. 6.2 Conditioning of test samples and sequence of testing Before testing them, condition all test samples in accordance

33、with SANS 70, and then carry out the tests of 6.3 to 6.5 (inclusive) in the order in which they are given. 6.3 Dimensions With the sample laid flat and in a relaxed state, use a suitably graduated rule to determine the depth of the waistband. Fit the pantihose or knee-high on an appropriate leg-form

34、 (which usually comes with the machine used to determine other dimensions) and use a suitably graduated rule to determine the toe depth at the widest point, then use SANS 5766 to determine the other dimensions. Report any seam cracking or seam breakdown that occurs on any of the test specimens (see

35、5.1). 6.4 Fibre composition Determine by microscopical examination and chemical analysis of representative yarns and threads.

39、 following information shall appear in legible and indelible marking on the outside of each bulk container, and shall be visible when the containers are stacked: a) the information required in terms of 7.2.1(a), (b), (c) and (d); b) a verbal description, for example “Pantihose“; and c) the amount of

40、 pantihose or knee-highs. 7.2.3 Additional marking When so required (see A.1(g) of annex A), envelopes or bulk containers, or both, shall bear information additional to that specified in 7.2.1 and 7.2.2. SANS 1242:2008 Edition 2.2 9 Annex A (normative) Notes to purchasers A.1 The following requireme

41、nts shall be specified in tender invitations and in each order and contract: a) whether the pantihose are to be supplied with or without a gusset (see 5.2); b) the colour (see 5.3); c) in the case of pantihose, the size and, in the case of the extra super large size, the type (see 5.4.1.1); d) in th

42、e case of knee-highs, the type (see 5.4.1.2); e) whether pantihose or knee-highs are to be supplied in single or multiple packs (see 7.1); f) whether pantihose of more than one size may be packed in a bulk container (see 7.1); and g) additional marking, if required (see 7.2.3). A.2 The following req

43、uirement shall be agreed upon between the purchaser and the supplier: the linear density and the number of filaments of the knitting yarns (see 4.1.2). Annex B (informative) Care and maintenance of pantihose or knee-highs The following are suggested instructions for the care and maintenance of panti

44、hose or knee-highs: Wash the pantihose or knee-highs with soap in lukewarm water, rinse well, and squeeze out the water without distorting the pantihose or knee-highs. Do not dry them in the sun or in front of a heater. SANS 1242:2008 Edition 2.2 10 Annex C (informative) Guidance for manufacturers a

45、nd purchasers of pantihose or knee-highs C.1 Pantihose or knee-highs that comply with the requirements of this standard have been produced by the use of the following: C.1.1 Yarns The yarns have a crimp rigidity3)of not less than 48 % and are of the following linear densities: a) for normal qualitie

46、s: 1) for the panty section of pantihose: 33 dtex f 10; and 2) for the legs: 17 dtex f 5 or 20 dtex f 7; b) for heavier qualities: 1) for the panty section of pantihose: 44 dtex f 13; and 2) for the legs: 33 dtex f 10. C.1.2 Structure Micromesh structure is used in the panty part of pantihose. (This

47、 provides greater widthwise extensibility than a plain jersey fabric.) C.1.3 Sewing thread The sewing threads used are continuous-filament synthetic threads of a linear density sufficient to give the required seam strength and extensibility. C.2 When the required extensibility and dimensions of pant

48、ihose cannot be otherwise attained, the sewing-in of one of the following types of gusset is recommended: a) for normal sizes: a gusset of suitable dimensions and that is sewn in at the crotch; and b) for the larger sizes: a panel gusset, i.e. either 1) a long gusset with parallel sides that extends

49、 over half of the crotch length at the back of the pantihose, or 2) a full panel gusset that extends over the whole of the crotch length (front to back). C.3 The finishing procedure, known as “semi-boarding“, increases the resistance to snagging, improves the appearance, and preserves elasticity. C.4 In the case of extra super large pantihose, this size has been subdivided into two types, which differ in terms of the dimensions of the panty section (see tab
