About this research
Extends earlier work on Rz to assess which roughness parameters best help interpret wet slip resistance for different classes of flooring.
How the research was conducted
The HSL team examined relationships between portable roughness measurements and wet pendulum values, including comparisons of hard and compliant floors and complex textured finishes.
Main findings and significance
The findings confirmed the continued usefulness of Rz for many floors, while identifying opportunities for other parameters to provide more detail on selected hard or etched surfaces.
Interpretation and limitations
A linked follow-on to RR549, demonstrating that a measurement parameter must be selected for the surface and application rather than treated as universally predictive.
