1.1This 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.
1.2There is no single combination of stain and fabric that will predict the overall performance of a product or treatment method. A single test, even with a variety of stains/fabrics, can only predict how products or treatment methods compare under the particular conditions chosen for evaluations. A series of assessments is necessary to evaluate the many aspects of stain removal performance and to simulate consumer experience more closely.
1.3In this guide, the use of both traditional top-loader washing machines as well as front and top-loading high-efficiency washers is addressed.
1.4The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
