The PTV is the score the pendulum records as its rubber slider crosses the floor — a measure of available friction. A higher PTV means more grip. In the wet, 36 or above is treated as low slip risk, 25–35 as moderate and 0–24 as high.
Wet. Almost any floor grips when dry; slips happen when a floor is wet or contaminated, so the meaningful test is carried out in the wet.
No law names the test itself, but the Workplace (Health, Safety and Welfare) Regulations 1992 and wider health-and-safety law require you to assess and control slip risk. A pendulum report is the recognised way to evidence that.
Both are recognised. The pendulum is the definitive method in BS 7976-2 / BS EN 16165; SlipAlert is a faster screening tool that correlates to the pendulum and is useful over large areas, with the pendulum used to confirm.
No. We are an independent UKAS-accredited testing laboratory with no flooring or anti-slip products to sell, so our results carry no commercial bias.
Testing is non-destructive and quick per area. We can work around opening hours and quiet periods so your operation keeps running.
The PTV for each area, the slider used, the directions tested, the wet and dry results and the site conditions, plus the HSE slip-potential classification and clear recommendations.
BS 7976-2, alongside BS EN 16165, following HSE and UK Slip Resistance Group (UKSRG) guidance, under our UKAS accreditation (Lab No. 7933).
