Everything You Need to Know About the Hydrostatic Head Tester
A hydrostatic head tester evaluates the waterproof capability of textiles, automotive interiors, and industrial materials. This guide covers its working principle, core components, global test standards (ISO, AATCC, EN), and a detailed testing procedure to ensure accurate results.
Water Resistance Testing Standards and Methods
Textile water resistance testing evaluates fabrics through three primary methods: hydrostatic pressure (measuring water penetration resistance), spray rating (assessing surface water repellency), and water repellency tests (quantifying water absorption). Hydrostatic pressure testing is critical for high-performance applications like outdoor apparel and diving gear, while spray rating evaluates surface staining for rainwear. Water repellency tests, such as the Bundesmann method, determine overall
