British pendulum tester

ASTM E 303. 2008. Standard test method for measuring surface frictional properties using the British Pendulum tester. West Conshohocken, PA ASTM International. 

Several ASTM standards give methods of pavement testing and methods of result calculation. A British pendulum tester is used to measure surface frictional properties. The pendulum slider is positioned in contact with the tested surface which was previously thoroughly cleaned and wetted. A rubber slider gliding on the surface causes a swing of the drag point, which increases with surface fiic-...

Finally, apart from the mobile devices, portable devices such as the British pendulum (SRT), the Japanese DFT (Dynamic Friction Tester) and the Swedish T2GO and VTI are in use. From the above, the British pendulum has been widely used in many countries around the world and the portable friction testers T2GO and VTI are slowly gaining popularity.
