Independent, UKAS-accredited pendulum testing at Guildford (GLD) — 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.
Guildford is the principal Surrey commuter station with c. 7 million annual passengers across 8 platforms.
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 Guildford, 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 Guildford 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
