The Inside Drum Friction Tester evaluates the friction characteristics of test piece on a road surface formed inside a rotating drum. The test piece is made to contact the drum at a specified load and applied a slip ratio. The torque applied to the sample when a test is conducted under such conditions is used to measure the friction force. The drum surface can be used to simulate ice, wet or dry road surface conditions.
Test Speed: 0.1 to 40km/h (Test Piece)
Slip Ratio: 0 to ±100%
