About this research
Investigates whether alternative surface roughness parameters can complement Rz and pendulum testing when assessing wet slip potential.
How the research was conducted
HSL measured a range of floor surfaces using its established pendulum and surface microroughness techniques, and compared other parameters available on portable profilometers.
Main findings and significance
The report tests the strength and practical value of relationships between alternative roughness metrics and wet pendulum measurements. It supports careful interpretation of surface texture, particularly where a single scalar roughness value cannot describe the complete contact.
Interpretation and limitations
Part of a linked research programme with RR732. It is a method-development study, not evidence of direct workplace accident reduction.
