PENDULUM SKID TESTER
The PENDULUM 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 Pendulum Skid 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 of the sample surface. A reading of Skid
Resistance Values is obtained.
