Send us a sample of your surface — decking, tile, paving, LVT, GRP, manhole cover — and we measure its slip resistance by pendulum to BS 7976-2 and EN 16165. You get back a UKAS-accredited report with a clear Pendulum Test Value (PTV) for the wet and the dry.
We test loose samples and offcuts of almost any pedestrian surface product, in the dry and — most importantly — in the wet, where the majority of slip claims arise. Pick your surface for the detail.
A simple, tracked process. Most standard jobs are tested and reported within a few working days of the sample reaching the lab.
Complete the sample form, then post or courier your sample to the lab. We confirm receipt with a unique reference.
The sample is conditioned, then pendulum-tested dry and wet using the correct slider for the surface and end use.
Results are converted to a mean PTV and interpreted against UKSRG slip-potential bands for the relevant conditions.
You receive a UKAS-accredited PDF report with method, results, photos and a clear slip-potential classification.
The pendulum simulates a heel strike. The higher the value, the lower the chance of slipping. UK courts, the HSE and the UK Slip Resistance Group all read results against the same bands.
High slip potential. Roughly a 1-in-20 chance of slipping or worse — generally unacceptable for pedestrian use when wet.
Moderate slip potential. A meaningful risk that usually needs control measures or a better surface.
Low slip potential. The widely accepted target for level pedestrian surfaces in the wet.
Barefoot wet areas (e.g. pool surrounds, changing rooms) are assessed with the TRL/55 slider against separate criteria. We confirm the correct slider and conditions for your product before testing, and can also measure surface roughness (Rz) as a supporting indicator.
Our scope of accreditation covers the pendulum methods relied on across UK and European flooring specification, litigation and product approval.
The core British Standard governing how the portable pendulum is operated and calibrated for slip resistance measurement.
The European standard consolidating slip resistance evaluation methods, including the pendulum (Annex C) for surface products.
Pendulum measurement applied to road, pavement and external surfacing — relevant to paving and external products.
The interpretation framework that turns raw PTV figures into the slip-potential classifications used in reports and disputes.
Tell us about your product and its intended use. We'll confirm the method, price and where to send your sample.
