Pendulum testing
across Cambridgeshire.

Why Cambridgeshire needs real PTV data.

Hospitals, care homes and universities across Cambridgeshire operate 24/7 with mixed footwear, wet-cleaning regimes and vulnerable users. A PTV of 36+ in both wet and dry states is the baseline — anything less is a CQC, HSE or insurance conversation waiting to happen.

The Cambridge biotech cluster plus the Peterborough distribution and food-processing corridor.

Pendulum testing. Not opinion.

The pendulum method — defined in BS 7976 and BS EN 16165, and referenced throughout HSE guidance — is the only test HSE considers reliable on wet or contaminated floors. A rubber slider swings from a fixed height and drags across the test surface for exactly 127mm; energy lost to friction is recorded as a Pendulum Test Value (PTV) on a scale of 0 to 150.

HSE classifies any PTV below 25 as a high slip potential. 25–35 is moderate. A PTV of 36 or above, measured wet and dry with the correct reference slider, is the benchmark for a floor considered safe under normal use. Every report we produce in Cambridgeshire is issued under our UKAS ISO/IEC 17025 accreditation (Lab 7933) — the method, the technician and the equipment are all independently audited.
