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 Acelereted Polishing machine (see link to other product below) 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/A: conforming to ASTM E303 standard and
• 48-PV0190/E: conforming to EN 1097-8 and all other mentioned EN standards

The pendulum is supplied complete with:

• Additional scale for tests on Polished Stone Value specimens
• Thermometer 0 to 220°C for surface temperature measurement
• Washing bottle, 1 l cap. for surface wetting
• Tool set with case for machine assembly
• Rule for sliding length verification
• Carrying case
• Traceable certificate of conformity to EN 1097-8 o ASTM E303

Three rubber sliders for site use are included.

• Case dimensions: 790x760x320 mm
• Weight approx. including case: 34 kg
