Twenty in-depth technical guides covering the pendulum test method, the standards, slider selection, R-ratings, surface roughness, expert evidence and report defensibility. Written from in-house UKAS-accredited testing experience.
What the Pendulum Test Value actually measures, the HSE bands and how specifications use them.
Read the guide →The current UK standard for the pendulum test method. Replaces BS 7976-2 since 2022.
Read the guide →What UKAS accreditation actually means, what it requires, and why it matters in court and to insurers.
Read the guide →When to use each slider type and why mis-selection invalidates the test.
Read the guide →When wet performance is binding, when dry is, and how the two together diagnose surface behaviour.
Read the guide →Class A, B, C ratings for pool surrounds, communal showers and changing rooms.
Read the guide →R9 to R13 industrial flooring ratings produced by the shod ramp test.
Read the guide →Portable tribometer testing under BS EN 16165 Annex D, and why it isn't the UK primary method.
Read the guide →Friction disc, slider conditioning, sweep distance and instrument level — what UKAS verifies.
Read the guide →Rz measurement, the HSE Rz/slip-risk correlation, and where Rz complements PTV.
Read the guide →R9 to R13 industrial flooring ratings, where they apply and how they relate to in-service pendulum data.
Read the guide →The 0-24, 25-35, 36+ bands, their derivation, and the regulatory weight HSE guidance carries.
Read the guide →The Civil Procedure Rules governing expert evidence in UK slip-claim litigation.
Read the guide →How surface preparation choices affect PTV results, in service and in forensic contexts.
Read the guide →Water, oil, soap, sugar, dust and biological contamination — each has its own slip-risk profile.
Read the guide →How cleaning chemistry affects in-service PTV, sometimes by tens of points either way.
Read the guide →Sealers, resin coatings, polishes and anti-slip treatments — what each does to PTV.
Read the guide →Best-practice PTV targets for retail, healthcare, care homes, kitchens, pools, transport and more.
Read the guide →Why UK practice favours the pendulum, when tribometer data adds value, and how they compare.
