Scope of standard 1.1 This guide provides direction for measuring the ability of detergents to prevent the deposition of soils from detergent solutions onto fabrics. It is intended as a laboratory screening test to aid in the formulation of detergent products, for quality control, and as a basis between the purchaser and seller in standardizing specific products' performance. 1.2 The anti-soil deposition performance of detergent products will vary greatly depending on the type of soils and fabrics used in the test. Therefore, selection of the soils, fabrics, reference detergents, and test conditions shall be made by agreement between the interested parties on the basis of experience. 1.3 There is no single or combination of oily soils or particulate soils, or both, that will precisely predict overall the performance of a product or treatment with respect to anti-redeposition as perceived by a consumer. This guide is intended to assess or compare detergent performance with respect to the anti-redeposition performance for the specific soil chosen. 1.4 The values stated in either inch-pound or SI units are to be regarded separately as the standard. The values given in parentheses are for information only. 1.5 This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Material safety data sheets are available for reagents and materials. Review them for hazards prior to usage. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
