This standard specifies methods for determining the colour fastness of textiles of all kinds, including five tests on different washing procedures from mild to severe, used for normal household articles. This standard is designed to determine the effect of washing only on the colour fastness of the textile. It is not intended to reflect the result of the comprehensive laundering procedure.
