20、, at the latest by October1995, and conflicting national standards shall be withdrawn at the latest by October1995.

22、resistance of the colour of natural cellulose textiles to the action of severe bleaching with sodium chlorite as ordinarily employed in textile processing. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of I
23、SO105. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO105 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and

ISO 105-F10:1989, Textiles Tests for colour fastness PartF10: Specification for adjacent fabric: Multifibre. 3 Principle A specimen of the textile in con
26、tact with one or two specified adjacent fabrics is treated in a sodium chlorite solution, rinsed and dried. The change in colour of the specimen and the staining of the adjacent fabric(s) are assessed with the grey scales. 4 Apparatus and reagents 4.1 Glass container, fitted with a reflux condenser
27、or other means of reducing evaporation of the bath, thus preventing the need to modify the bath during the test. 4.2 Sodium chlorite solution, 2,5g/l, containing0,1g of acid sodium pyrophosphate per litre, brought topH3,5 with formic acid immediately before the test. The exact concentration of the s
28、odium chlorite employed is determined by titration with sodium thiosulfate solution. 4.3 Adjacent fabrics (see ISO105-A01:1989, sub-clause8.3). Either: 4.3.1 A multifibre adjacent fabric, complying with ISO105-F10. Or 4.3.2 Two single-fibre adjacent fabrics, complying with the relevant sections ofF0
29、1 toF08 of ISO105-F:1985, to be assessed for staining. 4.4 If required, a non-dyeable fabric (for example, polypropylene). 4.5 Grey scale for assessing change in colour, complying with ISO105-A02, and grey scale for assessing staining, complying with ISO105-A03. 5 Test specimen 5.1 If the textile to
30、 be tested is fabric, a) attach a specimen measuring40mm 100mm to a piece of the multifibre adjacent fabric (4.3.1), also measuring40mm 100mm, by sewing along one of the shorter sides, with the multifibre fabric next to the face of the specimen; or b) attach a specimen measuring40mm 100mm between th
31、e two single-fibre adjacent fabrics (4.3.2), also measuring40mm 100mm, by sewing along one of the shorter sides. 5.2 Where yarn or loose fibre is to be tested, take a mass of the yarn or loose fibre approximately equal to one-half of the combined mass of the adjacent fabrics and a) place it between
32、a40mm 100mm piece of the multifibre adjacent fabric and a40mm 100mm piece of the non-dyeable fabric (4.4) and sew them along all four sides (seeISOA01:1989, subclause9.6); or b) place it between a40mm 100mm piece of each of the two specified single-fibre fabrics and sew along all four sides. 6 Proce
33、dure 6.1 Wet out the composite specimen in the sodium chlorite solution (4.2) and immerse it in the solution for1h without agitation, at a temperature of80 C 2 C and at a liquor ratio of50:1.EN ISO 105-N04:1995 4 BSI 11-1999 6.2 Rinse the composite specimen for10min in cold, running tap-water. Open
34、out the composite specimen by breaking the stitching on all sides except one of the shorter sides and dry by hanging it in air at a temperature not exceeding60 C with the parts in contact only at the remaining line of stitching. 6.3 Assess the change in colour of the specimen and the staining of the
35、 adjacent fabric(s) with the grey scales (4.5). 7 Test report The test report shall include the following particulars: a) the number and date of publication of this part of ISO105, i.e.ISO105-N04:1993; b) all details necessary for the identification of the sample tested; c) the numerical rating for
36、the change in colour of the specimen; d) if single-fibre adjacent fabrics were used, the numerical rating for staining of each kind of adjacent fabric used; e) if a multifibre adjacent fabric was used, the type of multifibre adjacent fabric used and the staining of each type of fibre in the multifib
