This guide can be used for simple screening of fabric softener products, or to evaluate the products through multiple accumulative cycles.

1.2The relative ranking of products assessed by these procedures may be affected by such factors as fabric load composition and the kind and level of soils, as well as by the washing and drying procedures used.

1.3The 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.

1.4This 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.
