The wet pendulum test is one of the most recognised methods used to assess the slip resistance of pedestrian floor surfaces in wet conditions.
The wet pendulum friction tester was originally developed to measure the skid resistance of road surfaces. It is now widely used to assess pedestrian flooring surfaces and help determine the risk of slipping.
The test uses a swinging arm fitted with a rubber slider. As the slider moves across the wet surface, the device measures the resistance between the rubber and the floor. The result helps indicate how slippery the surface may be.
Wet pendulum testing is commonly used for assessing both new and existing pedestrian surfaces under Australian slip resistance standards.
The floor surface is tested in a wet condition by applying water to the testing area. The pendulum is then released and allowed to swing across the surface multiple times.
A series of readings are recorded, and the average result is used to determine the slip resistance classification of the tested surface.
The testing area is inspected and prepared before water is applied.
The pendulum tester is used to measure resistance across the wet surface.
Readings are recorded and presented in a clear professional report.
Although the equipment may appear simple, accurate results depend on correct setup, calibration, operator training and testing technique. Incorrect testing can significantly affect the final slip rating.
