International Colorfastness Test Methods.

This first of a two-part series on international test methods for colorfastness discusses the necessity and desirability of international standardization, and reviews the role played by the International Organization for Standardization in developing test methods used throughout the world. A comparison is given of ISO and AATCC test methods for colorfastness of textiles. General principles of testing, tolerances and assessment of colorfastness are covered, followed by comparisons of the scope and principles of individual ISO and AATCC test methods for evaluating colorfastness to acids and alkalis, bleaching, carbonizing, light, mercerizing and metals in the dyebath.
