The instrument is now used in many other
applications to test the slip resistance on
pedestrian walkways and flooring, within offices,
hospitals, shopping malls and factories, both
at the design stage and also in the investigation
of accidents.
It 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.
Machine Operation The 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.
