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。它测量了水通过冲击渗透的阻力，因此可以用来预测织物可能的雨水渗透阻力。它特别适用于测量服装面料的抗渗透性。使用该仪器，可以在不同强度（见11.1）的水冲击下进行测试，以给出单一织物或织物组合的抗渗透性的完整整体图。本试验方法的结果取决于纤维和纱线的防水性，以及织物的结构。

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 to the penetration of water by impact, and thus can be used to predict the probable rain penetration resistance of fabrics. It is especially suitable for measuring the penetration resistance of garment fabrics. With the instrument, tests may be made at different intensities (see 11.1) of water impact to give acomplete overall picture of the penetration resistance of a single fabric or a combination of fabrics.The results obtained with this test method depend on the water repellency of the fibers and yarns, and on the construction of the fabric.
