Slip testing
in Dover.

Why Dover needs real PTV data.

Dover's port, quayside and marine engineering operations combine saltwater, diesel, grease and hydraulic oil — the hardest possible environment for a floor to stay compliant in. Pendulum testing is the only method HSE considers reliable under these contamination conditions.

Marine operators in Dover know that standard slip tests are designed for dry terrestrial environments. Pendulum testing, with appropriate slider selection, is the only method that survives audit in a working port.

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