Skid resistance test stand CRT-PENDULUM

The Cooper Wessex skid resistance tester CRT-PENDULUM is the original, the most widely used, and the best portable skid resistance tester in the world. The Cooper-Wessex Pendulum Skid Tester CRT-PENDULUM is the established 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 for the testing of road surfaces. The PST measures the frictional resistance between a rubber slider mounted on the end of a pendulum arm and the test surface. This provides highway engineers with a routine method of checking the resistance of wet and dry surfaces to slipping and skidding, both in the lab and on site. It is based on the Izod principle: a pendulum rotates about a spindle attached to a vertical pillar. At the end of the tubular arm a head of known 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 is obtained. Key Features Made in England by the experts Precision engineered, and perfected over 50 years Low friction arm, and lightweight pointer Designed for laboratory and in situ road surface testing Dispatched calibrated to EN1097-8 (accredited under ISO 9001:2000) Comes with integral F scale for use with small slider set for 76mm slide length. (PSV test) Repeatable and reproducible Supplied with robust carrying case This is the industry standard pendulum against which the often poor imitations are judged
