ASTM D4250-92(2003) (R1992)

1.1 This test method is designed for determining the water-holding capacity, C _wh, of bibulous papers such as facial tissues, towels, wipes, nonwovens, etc., using predetermined times of soaking and excess water extraction under a predetermined low suction head resulting from a controlled capillary draining action.

1.2 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.

This test method provides a measure of the ability of a towel, or like material, to soak up water in the drying of surfaces, absorption of spills, etc.

Water-holding capacity, as measured by this method, discriminates well among different absorbing products.
