This standard specifies a test method for color fastness to rubbing, designed for textiles with small areas or complex patterns, such as prints, patches, or narrow cut pieces. It defines a smaller test area compared to conventional color fastness to rubbing tests. The standard includes procedures for both dry and wet rubbing tests. In practical testing, a reciprocating rubbing color fastness tester is required. Such instruments are typically equipped with friction heads of specific dimensions, capable of repeatedly rubbing the sample under fixed pressure, stroke, and speed. After testing, the staining of the rubbing cloth is graded according to the standard grey scale to evaluate the color durability of the textile.
