Used for the measurement of surface friction properties, the apparatus is suitable for both side  and laboratory applications and for Polished Stone Value (PSV) using curved specimens from accelerated polishing test with the  accelerated polishing machine. During operation the pendulum is raised and then allowed to swing freely, allowing the edge of the rubber slider to skid across the surface of the road or sample. 

The pendulum is supplied complete with:

Additional scale for tests on Polished Stone Value specimens

Washing bottle, 1 l cap. for surface wetting

Tool set with case for machine assembly

Thermometer 0 to 220°C for surface temperature measurement

Rule for sliding length verification

Carrying case

Case dimensions: 790x760x320 mm
