GB/T 420-2009 "Textiles - Tests for colour fastness - Colour fastness to brushing for pigment printed textiles" specifies a test method for determining the resistance of pigment printed textiles to domestic brushing. The specimen is brushed back and forth a specified number of times with a nylon brush under a certain pressure in a soap solution. After drying, the degree of colour change is assessed to evaluate the resistance of such printed fabrics (especially pigment prints) to washing and rubbing.
