This Standard specifies two test methods for determination of colour fastness transfer in joints of textiles, i.e. washing method and immersion method.
This Standard is applicable to all kinds of textiles made by patchwork of deep and light colour fabrics. Other textiles may also refer to the provisions of this Standard.
