This document specifies test methods to measure the amount of test liquid (simulated urine) which runs down a nonwoven test specimen when a specified mass of test liquid is poured on the nonwoven test specimen superimposed on a standard absorbent medium and placed on an inclined plane.
u000bThis document is designed to compare run-off of nonwovens. It is not intended to simulate in use conditions for finished products.
u000bThe three methods are:
u000ba) Option A - basic method for testing hydrophilic nonwovens, see AnnexA.
u000bb) Option B - repeated test, with the same test parameters as the basic method with additional information in Option A, see AnnexB.
u000bc) Option C - modified method for testing hydrophobic nonwovens specifying another degree of incline, see AnnexC.
u000bThe test method is designed to measure the repellency of hydrophobic nonwovens. At the standard inclination angle, Option A isn’t able to distinguish between different levels of hydrophobicity. By decreasing the inclination of the table, one can assess the difference in repellence of hydrophobic nonwovens.
u000bFor RD purposes, other characteristics can be measured according to AnnexD.
