BS7976 Pendulum Test
How does it work?
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.
Scientific basis of measurement
The Pendulum 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.

Slip testing should not just be a one off requirement in response to an accident or slip incident but should become part of your routine ongoing proactive safety regime. If required we can carry this out on a regular basis.
