This method assesses the resistance of the colour of textile materials to rubbing off in the dry state or in the presence of moisture or solvent. Such rubbing off of colour may result in fading or streaking, and/or staining of other materials.

This method is not recommended for the testing of carpets. A method assessing the colourfastness to crocking of carpets may be found in CAN/CGSB-4.161, Appendix B.

The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.

Washing, drycleaning, ironing, finishing, etc. may affect the degree of colour transfer from a material. The test may be done before, after, or before and after any such treatment.
