<p>ISO 18696:2006 is applicable to any textile fabric, which may or may not have been given a water-resistant or water-repellent finish. It measures the resistance of fabrics to wetting by water by the tumble-jar absorption test. It is particularly suitable for measuring the water-repellent efficacy of finishes applied to fabrics, because it subjects the treated fabrics to dynamic conditions similar to those often encountered during actual use.</p>
<p>The test is not intended for use in predicting rain-penetration resistance of fabrics, since it measures absorption of water into, but not through, the fabric. It is intended to determine a fabric's ability to resist water absorption and can be used to predict the probable weight gain of a garment in actual use. The test is best suited for fabrics used in garments for severe wet environmental conditions over an extended time.</p>
