Purpose and Scope

This test method (see 11.1) is intended for evaluating the resistance of colored fabrics to change in shade caused by flat abrasion. It can be used for all colored fabrics, but is especially sensitive to the color change of durable press crossdyed blend fabrics, in which one fiber is abraded away faster than another. 

The test method produces in an accelerated manner, a localized color change similar to that produced on some garments over relatively short periods of actual wear in which the garment is exposed to relatively mild abrasive action (see 11.2).
