BS EN ISO 105-E09:2010 specifies a method for determining the resistance of the colour of textiles of all kinds and in all forms to the action of boiling water.
BS EN ISO 105-E09:2010 is mainly applicable to wool and textiles containing wool.
A specimen of the textile between adjacent fabrics is rolled around a glass rod and treated with boiling water. The specimen and the adjacent fabrics are dried separately. The change in colour of the specimen and the staining of the adjacent fabrics are assessed with the grey scales or instrumentally.
7.1 RoIl the composite specimen compactly around the glass rod to form a cylinder (40 ± 2) mm long and tie it uniformly, but not tightly, with thread.
7.2 Treat the specimen on the rod for I h in boiling water (5.1), at a liquor ratio of 30:1, under reflux.
7.3 Open out the composite specimen (by breaking the stitching on all sides, except one of the shorter sides, if necessary) and dry it by hanging it in the air at a temperature not exceeding 60 °C, with the three parts in contact only at the line of stitching.
7.4 Assess the change in colour of the specimen and the staining of the adjacent fabric(s) with reference to the original specimen and adjacent fabric(s) by comparison with the grey scales (4.5 and 4.6) and/or instrumentally (see 4.7).
