ISO 22958:2021 PDF

Scope: This document specifies a test for measuring the resistance of fabrics to the penetration of water by impact. It can be used to predict the probable rain penetration resistance of textile fabrics. This document is applicable to any textile fabric, whether or not it has been given a water-resistant or water-repellent finish. It is especially suitable for measuring apparel fabrics. Testing at different intensities of water impact gives a complete picture of the penetration resistance of a single fabric or combination of fabrics. The test is particularly suitable when measuring highly water-resistant fabrics with low amounts of water penetration.
