22、ffect, on the colour of a dye, of dyeing in the presence of hexavalent chromium salts. It is applicable to wool. An alternative method is specified in6.3 to provide a milder test suitable for assessing the effect of chromium salts in such concentrations as might be found when shading. 2 Normative re

25、2:1993, Textiles Tests for colour fastness PartA02: Grey scale for assessing change in colour. 3 Principle The difference in colour between dyeings made with and without potassium dichromate is assessed with the grey scale. 4 Apparatus and reagents 4.1 Two pieces of undyed light wool fabric, of a si
26、ze suitable for laboratory dyeing. 4.2 Two dye-baths, and solutions usual for the dye. 4.3 Potassium dichromate (K 2 Cr 2 O 7 ),10g/l solution. 4.4 Grey scale for assessing change in colour, complying with ISO105-A02. 5 Test specimens See4.1. 6 Procedure 6.1 Dyeing Make two dyeings of the dye at the
27、 standard depth of colour on the wool fabric using the normal method for the dye under examination at a liquor ratio of40:1. 6.2 Method 1 On completion of the dyeing, add to one of the dye-baths sufficient potassium dichromate solution to give1% of K 2 Cr 2 O 7on the mass of the wool. Maintain both
28、baths at the boil for a further60min. 6.3 Method 2 On completion of the dyeing, add to one of the dye-baths sufficient potassium dichromate solution to give0,2% of K 2 Cr 2 O 7on the mass of the wool. Maintain both baths at the boil for a further60min. 6.4 Evaluation Compare the colour of the dyeing
29、 made in the presence of potassium dichromate with that of the dyeing made in its absence and assess the difference with the grey scale(4.4). 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-Z01:1993; b) t
30、he dye used; c) the method and the strength of the dyeing; d) the numerical rating for change in colour.EN ISO 105-Z01:1995 4 BSI 11-1999 Annex ZA (normative) Normative references to international publications with their relevant European publications This European Standard incorporates by dated or
