Skid Resistance & Friction Tester
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 conforming to EN 1097-8. It can also be used for testing Paving Stones (EN 1341, EN 1342) and Paving Blocks (EN 1338).
The apparatus, originally developed at the Transport and Research Laboratory, U.K., consists of an adjustable pendulum arm, and a spring loaded rubber slider (see accessories) mounted on the end of the arm. 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.
Two versions available:
48-PV0190/ASTM: conforming to ASTM E303 standard and
48-PV0190/EN: conforming to EN 1097-8 and all other mentioned EN standards
The pendulum is supplied complete with:
