PSV TESTS - PRODUCT RANGE

In accordance with BS EN 1097-8:2000, to determine the PSV it is necessary to use
the Skid Resistance Tester & Base Plate.

Skid Resistance Tester

Introduction
The Skid Resistance Tester was originally developed by the Transport Research
Laboratory (TRL) to study the problems in design and maintenance of public
highways. It's also known as the British Pendulum Tester, Portable Skid Resistance
Tester and the Pendulum Tester.
The Skid Resistance Tester is used to test the Skid Resistance Value (SRV) of
existing road surfaces.
The Skid Resistance Tester measures the frictional resistance between a rubber
slider mounted on the end of a pendulum arm and the test surface. This provides
highway and flooring engineers with a routine method of checking the resistance of
wet and dry surfaces to slipping and skidding.
The Skid Resistance Tester has a robust and rigid design for protection against wear
and tear, weathering and dirt contamination.
The instrument is now used in many applications to test the slip resistance on
pedestrian walkways and flooring, within offices, hospitals, shopping centres and
factories, both at the design stage and also in the investigation of accidents.

Machine Operation

The Skid Resistance Tester is based on the Izod principle. A pendulum consisting of
a tubular arm rotates about a spindle attached to a vertical pillar. At the end of the
tubular arm a head of constant mass is fitted with a rubber slider. The pendulum is
released from a horizontal position so that it strikes the sample surface with a
constant velocity. The distance travelled by the head after striking the sample, is
determined by the friction to the sample surface. A reading of Skid Resistance
Values is obtained.
