About Bundesmann Water Repellency Tester
The Bundesmann water repellency tester is used to determine resistance to wetting and resistance to penetration by water of water repellent fabrics which are permeable to air.
In this test, four test specimens taken from the fabric under test are simultaneously exposed to a simulated heavy shower of controlled intensity while the lower surface of each specimen is subjected to a rubbing action. The increase in mass of the specimen during exposure to the shower is determined and any water passing through the fabric collected and its volume determined.

FAQs of Bundesmann Water Repellency Tester:
Q: How does the Bundesmann Water Repellency Tester evaluate textiles?
A: The tester exposes fabric specimens to a controlled spray of waterat 60 rpm rotation and a water flow of 600 ml/min per nozzlefor a 10-minute cycle, simulating real-world rainfall conditions. The amount of water penetration and surface wetting is measured, providing a reliable assessment of fabric water repellency.
Q: What types of materials can be tested with this instrument?
A: The Bundesmann Water Repellency Tester is suitable for a broad range of fabrics, including textiles, nonwovens, and technical fabrics. Its design accommodates specimens up to 200 mm in diameter, allowing comprehensive evaluation for various applications.
Q: When should a water repellency test be conducted on fabrics?
A: Testing is recommended during product development, quality control, and before shipment to ensure materials meet specific water resistance standards required by end-use or customer specifications.
Q: Where is the ideal environment to operate this tester?
A: The instrument is designed for use in textile and fabric testing laboratories with ambient conditions up to 35C temperature and relative humidity as high as 95%. It requires stable electric power for optimal performance.
Q: What is the operational process for conducting a test?
A: To conduct a test, place up to four specimens in the holder, set the digital timer, and adjust test parameters as needed. Water is sprayed from a height of 1500 mm, and the disc rotates at the pre-set speed. Observable through transparent acrylic windows, the cycle runs for 10 minutes before results are analyzed.
Q: How can using this tester benefit manufacturers and suppliers?
A: By delivering consistent and standardized assessments of material water repellency, the tester helps manufacturers and suppliers maintain quality control, meet international market requirements, and minimize customer complaints related to fabric performance.
Q: What features support accurate test monitoring and results?
A: The device provides real-time monitoring with its digital timer, RPM indicator, and transparent acrylic observation windows, allowing users to inspect specimen behavior and ensure strict adherence to prescribed test conditions.
