Scope

This Standard specifies the test method to measure the fabric resistance to water
penetration under the low impact conditions. This method can be used to predict the
anti-rain and pervaporation properties of fabrics.
This Standard is applicable to the fabrics been subject to or not been subject to the
waterproof or water repellent finishing. Compared with severe-role of Bounds method
(GB/T 14577) or leaching method (GB/T 23321), this method is more suitable for
fabrics with medium loose structures.
This Standard is not applicable to the fabrics that can’t be flattened under certain
tension conditions.

Summary	This standard specifies the test method for testing the impermeability of fabrics under low impact conditions. The method can be used to predict the anti-rainy osmotic properties of fabrics. This standard applies to all types of fabrics that have not been subjected to water repellent finishing or water repellent finishing. This method is more suitable for medium-loose fabrics than the Bondier method (GB/T 14577) or the leaching method (GB/T 23321), which is more severe. This standard does not apply to fabrics that can not be flattened under certain tension conditions.
