Textiles — Tests for colour fastness — Part Z01: Colour fastness to metals in the dye-bath: Chromium salts

This test method is intended for determining the effect on the colour of a dye of dyeing in the presence of hexavalent chromium salts. It is applicable to wool. An alternative test method is specified in 6.3 to provide a milder test suitable for assessing the effect of chromium salts in such concentrations as might be found when shading.
