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/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:
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
Main features
New low friction release mechanism of the pendulum arm for beter accuracy
Extremely light pointer, for high precision results.
Slider lifting system integrated in the pendulum foot that guarantees reliable adjustment operations
Stiff and stout twin column structure
Easy and reliable height adjusting system
Integrated additional scale for tests on PSV specimens
Complete with calibration certificate to EN 1097-8 or ASTM E303
