Bundesmann Water Repellency Tester

The Bundesmann Water Repellency Tester measures the water resistance of fabrics under simulated rainfall and dynamic motion. It evaluates how much water penetrates through the fabric and how much it absorbs during testing. The tester features automatic flow rate control, internal water recycling, and wiper speed, and specimen rotation. Designed for accuracy and repeatability, it provides reliable performance for outdoor apparel, coated textiles, raincoats, and diving suits. With compliance to ISO 9865, DIN EN 29865, GB/T 14577, and BS EN 29865, this machine delivers professional-grade testing for textile manufacturers and research laboratories.
