CAN/CGSB-4.2 No. 18.2-2010/ ISO 105-B01: 1994

This National Standard of Canada is equivalent to International Standard ISO 105-B01:1994. 1 Scope This part of ISO 105 specifies a method intended for determining the resistance of the colour of textiles of all kinds and in all forms to the action of daylight. This method allows the use of two different sets of blue wool references. The result from the two different sets of references may not be identical. NOTE 1: General information on colour fastness to light is given in annex A.
