Features of the Bundesmann Water Repellency Tester RF4468:
-
The Bundesmann Water Repellency Tester RF4468 is designed to evaluate the water repellency of fabrics when exposed to simulated rainfall under dynamic conditions (the fabric is subjected to rubbing and friction underneath).
- The fabric sample is securely clamped on a test cup, beneath which a rotating wiper mechanism applies friction to the back side of the fabric to simulate the effects of rubbing, allowing the assessment of water penetration under combined rain and friction conditions.
- After the test, the amount of water that has penetrated through the fabric is collected in the cup below, or the amount of water absorbed by the fabric is weighed to determine its water repellency performance.
