Description

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 standards and
48-PV0190/EN conforming to EN 1097-8 and 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 or ASTM E303

Rubber sliders for laboratory and site use are not included and have to be ordered separately. See accessories.
