本试验方法适用于任何可能或可能未进行防水或拒水整理的纺织面料。它测量织物对水的润湿性。它特别适用于测量织物整理剂的拒水效果，因为它使经过处理的织物处于与实际使用中经常遇到的情况类似的动态条件下。Its不适用于织物的防雨渗透性能，因为它测量的是织物对水的吸收，而不是通过织物。本试验方法获得的结果主要取决于织物中纤维和纱线的抗湿性或拒水性，而不是织物的结构。

This test method 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. 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. Its is not intended for use in probable rain penetration resistance of fabrics, since it measures absorption of water into, but not through, the fabric.The results obtained with this test method depend primarily on the resistance to wetting or water repellency of the fibers and yarns in the fabric, and not upon the construction of the fabric.
