ASTM D5548-99

Standard Guide for Evaluating Color Transfer or Color Loss of Dyed Fabrics in Laundering

SCOPE
1.1 This guide covers evaluating the effect of dyestuff color transfer or color loss from dyed fabrics. It is designed as a laboratory screening test to aid in the formulation of detergent products or in the comparison of two or more products.
1.2 There is no single assessment that will give the overall performance of a laundry product. A single test can only predict how products compare under the particular conditions chosen for evaluation and cannot be expected to reflect their comparative performance under the many other possible conditions of use. A series of assessments is always necessary in order to evaluate the many aspects of product performance. It is necessary to conduct confirming tests under controlled but practical home-laundering conditions to simulate consumer experience.
1.3 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.
1.4 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.
