The guide, as now constituted, is not suitable for ranking of detergent products since no basis is available at this time for correlation of the detergency performance of any particular soiled cloth or clothes with detergency of naturally soiled articles.
A suggested procedure for comparing the performance of any two laundry detergents on naturally soiled family items in home laundry equipment under controlled conditions on a paired comparison basis is described in Method D 2960
1.1 This is a guide for measuring the ability of detergents to remove artificially applied soils from 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 relative ranking of detergent products will vary greatly depending on the type of soiled fabrics used in the test. Therefore, selection of the standard soiled fabric to be used in a test shall be made by agreement between the interested parties on the basis of experience.
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 and health practices and determine the applicability of regulatory limitations prior to use.
