Slip testing
in Caerphilly.

Why Caerphilly needs real PTV data.

Caerphilly's industrial base — manufacturing and retail — exposes workers to the exact floor conditions where slip tests matter most: wet, contaminated, and in continuous use. A compliant PTV is not a design claim; it is a measured value under real-world conditions.

We test across Caerphilly's manufacturing estate regularly — advance bookings, night-shift work, and contaminant-specific testing are all routine. Production downtime is not required.

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; 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 Caerphilly is issued under our UKAS ISO/IEC 17025 accreditation — the method, the technician and the equipment are all independently audited.
