出版:British Standards Institution

专家解读视频
Gives a spray test method for determining the resistance of any fabric which may or may not have been given a water-resistant or water-repellent finish - to surface wetting by water. Not intended for use in predicting the rain penetration resistance of fabrics, since it does not measure penetration of water through the fabric. Covers reference, definition, principle, apparatus and materials, conditioning and testing atmospheres, test specimens, procedure and test report.
