AATCC Test Method 193-2012
Aqueous Liquid Repellency: Water/Alcohol
Solution Resistance Test
Developed in 2004 by AATCC Committee RA56 (Reaffirmed 2012)
1. Purpose and Scope
1.1 This test method can be used to determine the efficacy of a protective finish that is capable of imparting a low energy surface on all types of fabrics, by evaluating the fabric's resistance to wetting by a selected series of water/alcohol solutions of different surface tensions.
2.1 Drops of standard test liquids, consisting of a selected series of water/alcohol solutions with varying surface tensions, are placed on the fabric surface and observed for wetting, wicking and contact angle.
