British Pendulum Testers

The Portable Skid Resistance Tester – also known as the British Pendulum Tester – was originally designed in the 1940s by Percy Sigler to measure the slip resistance of floors in government buildings. During the late 1950s, the instrument was adopted and redesigned by the Road Research Laboratory (now known as the Transport Research Laboratory, TRL). Although basically unchanged, W F Stanley, now part of Munro Instruments Limited and known today as Munro Stanley London, has continually refined and improved the original design. The instrument is used to study problems in the design and maintenance of public highways, and to test the frictional resistance of new roads, road markings and iron works.

Another important application of the Pendulum Tester is to measure slip potential on pedestrian surfaces. Research by the Health and Safety Executive (HSE) has identified that in excess of 90% of slipping accidents in the UK occur on smooth, wet floors. The Portable Skid Resistance Tester is regularly used to test the slip resistance of pedestrian walkways in offices, shopping malls, factories, airports and sports facilities – both at the design stage and in the investigation of accidents.

We offer two types of Pendulum Tester. Our newest model – the Intelligent Pendulum – operates according to the exact same principle as the Portable Skid Resistance Tester, but has the added benefit of a digital display and software functionality.  It is the world’s first digitized Pendulum Tester.
