GB/T 5716-2013 "Textiles - Tests for colour fastness - Colour fastness to alkali spotting" specifies a test method for assessing the resistance of the colour of dyed textiles to the localized effects of a dilute sodium hydroxide solution. The test involves applying a drop of alkali solution to the specimen, removing the drop, and then drying. The degree of colour change at the treated area is evaluated using the grey scale, simulating the colour fastness of textiles when in contact with alkaline substances, such as soap or detergent residues.
