scope:

1.1 This is a guide for evaluating stain removal performance of home laundry products or home laundering conditions. It provides guidance for the selection, preparation, application, and examination of various types of stains on test fabrics that are subjected to controlled but practical stain removal treatment conditions.

1.2 There is no single type of stain that will predict the overall performance of a product or treatment method. A single test, even with a variety of stains, can only predict how products or treatment methods compare under the particular conditions chosen for evaluation. A series of assessments is necessary to evaluate the many aspects of stain removal per- formance and to simulate consumer experience more closely.

1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
