Independent, UKAS-accredited pendulum testing at Liverpool Lime Street (LIV) — covering platforms, copers, footbridges, ticket halls and subways. HSE-referenced PTV data that stands up at RAIB enquiry, in front of insurers and in court.
Liverpool Lime Street is the principal Merseyside terminus with c. 14 million annual passengers across 10 platforms — and the iconic listed Northern Hotel frontage.
Network Rail Property and TOC station managers use PTV reports as the documentary basis for slip-claims defence, post-incident review, and continuous-evidence safety records. At Liverpool Lime Street, that record turns on a single question every time a passenger slips: what was the PTV?
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 platforms. 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 any passenger-accessible station surface. Every report we produce at Liverpool Lime Street is issued under our UKAS ISO/IEC 17025 accreditation — the method, the technician and the equipment all independently audited.
"It is strongly recommended that [sled] tests are not used to assess the slipperiness of wet or contaminated floors. Such tests may produce misleading information when used in such conditions."— Health & Safety Executive · Slips Assessment Tool guidance
