How to test the waterproof performance? As a collectively owned research and testing institution, Baijian.com is capable of testing the waterproof performance, impermeability, moisture resistance, rain resistance, surface water repellency (spraying), impermeability (static water pressure), and liquid static pressure of coatings, fabrics, textiles, rolls, building materials, tents, wires and cables, equipment, and other services. It can conduct waterproof performance testing and issue waterproof performance testing reports. The testing cycle is short, and a waterproof performance testing report can be issued within 7-15 days. Low testing cost, scientific and reliable data, fair and rigorous, integrating testing, inspection, analysis, testing, technical consulting and other services, can carry out waterproof performance testing projects. Having the national high-tech enterprise certificate and CMA testing qualification certificate, with complete testing instruments, the testing report can be issued within 7-15 days Testing scope: Coatings, fabrics, textiles, rolls, building materials, tents, wires and cables, equipment, etc Testing items: Waterproof performance testing, impermeability, moisture resistance, rain resistance, surface water repellency (spraying), impermeability (static water pressure), liquid static pressure testing, etc Testing standards
