This document specifies a test method for the determination of the strike- through time (STT) for each of three subsequent doses of liquid (simulated urine) applied to the surface of a test specimen of nonwoven coverstock. The STT is defined as the time taken for a known volume of liquid to pass through the nonwoven that is in contact with an underlying dry standard absorbent pad. This test method is intended for Quality Control and is designed for comparison of STT for different nonwoven coverstocks. It does not simulate in-use conditions for finished products. SI values are regarded as the official standard system of measurement for this standard procedure. If other systems of measurement are used in place of SI units (including inch-pound), their values must be reported independently. Systems of measurement must not be combined in any way, but shall be regarded and reported separately.
