The internationally accepted test method for skid resistance measurement on all surfaces where people or vehicles may slip or skid. It also can be used for testing slip resistance of floors and sports surfaces.
The Pendulum is well established as a world leader in its field. Originally designed in the 1940s in the US, the instrument was further developed in the 1960s at the UK Transport Research Laboratory (TRRL) at the Department of Scientific and Industrial Research - a British Government organization concerned with studying problems that arise in designing, building, maintaining and using public highways.
Today it is the industry standard for a vast array of surface testing applications, including the testing of wooden decking. It is used in accident investigations, both traffic and pedestrian and Litigation investigations.
The instrument which gives a direct reading, gives a measure of the friction between a skidding tyre and wet road surface. It provides the Highway Engineer with a practical means of obtaining reliable scientific evidence on which to take the appropriate measures to reduce skidding.

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. The pendulum arm has a spring-loaded rubber slider on the pendulum foot. The Pendulum device is placed on the portion of the road/floor surface to be tested. It is then levelled, and the height of the centre of suspension of the pendulum is adjusted to a fixed value which is read on a special gauge. The pendulum is then released from its horizontal position, to swing down freely until the rubber slider contacts the test surface. As the slider travels across the surface for a fixed distance, the pendulum is slowed and a frictionally-constrained pointer affixed to the pendulum arm measures the highest point in the pendulum arc. The position of the pointer is then read on a measuring arc graduated from 0 to 150. Pointer readings indicate the resistance to skidding of the test surface.
