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.

Formerly under the jurisdiction of Committee D06 on Paper and Paper Products, this test method was withdrawn in December 2009 due to insufficient committee interest in reviewing and revising the standard.

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.

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.
