本试验方法旨在测量染色、印花或其他有色纺织纱线和织物的耐水性。 本试验方法中使用蒸馏水或去离子水，因为天然（自来水）的成分是可变的。试样由多纤维测试织物支撑，在规定的温度和时间条件下浸入水中，然后在规定的压力、温度和时间条件下放置在玻璃或塑料板之间。观察试样颜色的变化和附着的多纤维测试织物的染色情况。

This test method is designed to measure the resistance to water of dyed, printed, or otherwise colored textile yarns and fabrics. Distilled water or deionized water is used in this test method because natural (tap) water is variable in composition.The specimen, backed by multifiber test fabric, is immersed in water under specified conditions of temperature and time, and then placed between glass or plastic plates under specified conditions of pressure, temperature and time. The change in color of the specimen and the staining of the attached multifiber test fabric are observed.
