Description
Instrument for the determination of the slipperiness according to the standards. Portable instrument, designed and constructed to the requirements and can used  to test and give a direct reading measurement of: 1.  Testing of slip resistance of tiles and walkways (for this  measurement a special       (4-S) Four-S slider (Standard Simulated Shoe Sole) is used. Where the surface       roughness exceeds a certain value,the TRL slider may also be used as an alterna      tive to the (4-S) Four-S Slider. 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. The instrument is supplied “WITHOUT rubber slider, that have to be ordered separtately (see accessories below).
