Watch the video to see how to determine the coefficient of static friction with our measuring set for a PV mounting system on a flat roof.

• Tips for determining the coefficient of static friction
• Draw roof and measuring points
• Attach a test weight to the coefficient of friction block
• Spring tension balance
• Set scale of spring tension balance to 0
• Test 1 on dry surface
• Attach the spring tension scale
• Read off the data and record it in the protocol
• Test 2 on wet surface (same procedure as test 1)
• Calculation of the coefficient
• Enter values in planning software K2 Base
