Testing of Watertightness

The air - and watertightness of textile structures and other materials can be determined according to different international standards (EN 1928, EN 20811, EN ISO 9237).
For a fast and exact determination of the watertightness, we put in electronically controlled water-pressure-appliances. By the high-precise, electronically regulated pressure-sensor, a very high measuring-precision and reproducibility is guaranteed independently of the chosen procedure.
The thickness of the test-samples may vary from 0.01 mm to 45 mm.
