Pendulum Skid Resistance Tester

Product Description

The Cooper Wessex skid resistance tester CRT-PENDULUM is one of the best portable skid resistance tester The Cooper-Wessex Pendulum Skid Resistance Tester CRT-PENDULUM (also known as British Pendulum Tester or Portable Skid Tester) is one of the best portable skid resistance testing equipment in the world. Originally designed in the ***0s in the US, the instrument was further developed in the ***0s at the UK Transport Research Laboratory for the testing of road surfaces. The CRT-PENDULUM 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.
