Wet Pendulum Slip Testing

About the lab

Our NATA accredited wet pendulum slip testing facility specialises in conducting slip resistance tests in accordance to AS 4586 Appendix A, utilising advanced techniques and equipment including slider 55 and slider 96.

Slider 55 and slider 96 are two key components of our testing apparatus to provide precise measurements of slip resistance. Slider 96 is designed to simulate pedestrian shoe materials for pedestrian surfaces, and slider 55 is used to test slip resistance for barefoot surfaces such as bathrooms, pools, etc. These sliders undergo periodic calibration to ensure accuracy and consistency in our testing procedures.

The NCC requires pedestrian surfaces to be non-slip along trafficable areas and public entry and egress routes in buildings. This requires surfaces to be slip tested to AS 4586. Wet pendulum slip testing is performed on the surfaces to determine the slip resistance values. These measurements are then used to determine the non-slip suitability and compliance for the application.

Our comprehensive testing methodology involves subjecting surfaces to simulated wet conditions and measuring the slip resistance to provide valuable insights into surface safety.

Below is a classification table that categorises surfaces slip rating based on their slip resistance performance.

Wet Pendulum Slip Rating Wet Pendulum SRV Range
Slider 55 Slider 96
P0 < 12
P1 < 20 12 → 24
P2 20 → 34 25 → 34
P3 35 → 39 35 → 44
P4 40 → 44 45 → 54
P5 > 44 > 54

Wet pendulum slip testing can be conducted to the following standards
