16 in-depth technical guides covering the pendulum test method for pool environments, slider selection, surface roughness Rz, pool plant chemistry interaction, HSG179 alignment, expert evidence and report defensibility.
The Pendulum Test Value — PTV — is the single number produced by a pendulum test. For pool operators, interpreting PTV correctly is the difference between meaningful and misleading slip-resistance evi...
Read the guide →Pool pendulum testing differs from typical commercial floor testing in one critical respect: the slider. Pool users are barefoot or in soft footwear, and the relevant friction characteristics are wet-...
Read the guide →BS EN 16165:2021 Annex C is the current UK pendulum testing standard, replacing the long-established BS 7976-2 in February 2022. For pool operators, the practical effect is minimal — the pendulum test...
Read the guide →Surface roughness — the Rz value, measured in microns — describes the micro-texture of a floor surface. For pool surrounds it is a useful complement to pendulum testing, particularly in forensic and l...
Read the guide →Pendulum testing is conducted under wet and dry conditions as standard. For pool surrounds, the wet result is the only practically relevant value because pool surrounds are wet by definition. This gui...
Read the guide →Many UK pool slip testing providers are not UKAS accredited. The distinction is invisible to most pool operators until a report is challenged — by an insurer at renewal, by an opposing solicitor in a ...
Read the guide →HSG179 — Health and Safety in Swimming Pools — is the principal HSE guidance document for UK pool operators. While it does not prescribe specific pendulum thresholds, it requires risk assessment and a...
Read the guide →Pool surround surfaces in the UK estate include a wide range of tile and material types, each with characteristic slip-resistance profiles, ageing patterns and remediation options. This guide covers t...
Read the guide →Pool surrounds age differently to typical commercial floors because they sit in continuous contact with pool plant chemistry. Chlorine, salt cells, calcium hardness adjustments, pH control and periodi...
Read the guide →Part 35 of the Civil Procedure Rules governs expert evidence in UK civil proceedings. For pool slip claim litigation, where pendulum data and surround assessment are typically central, Part 35 complia...
Read the guide →When a pool surround has fallen below acceptable PTV but full replacement is not feasible (operational disruption, heritage constraints, budget), anti-slip treatment can restore compliance. This guide...
Read the guide →Pool surround cleaning is typically chosen for cleanliness, hygiene and pool plant compatibility — with slip resistance an afterthought or absent consideration. But cleaning chemistry directly affects...
Read the guide →A pool pendulum report is only as useful as the cross-examination it can survive. For any pool testing that may need to support a contested claim, regulatory compliance, or insurer requirements, the r...
Read the guide →A pendulum tester that is incorrectly calibrated produces incorrect PTV readings. The instrument's calibration regime — friction disc verification, slider conditioning, sweep distance check, level set...
Read the guide →Different pool zones warrant different PTV targets. The HSE 36+ wet baseline is the floor across most pool surrounds, but for vulnerable user populations, sloped surfaces, or high-consequence settings...
Read the guide →When a pool slip incident occurs, the immediate operational response is medical and managerial. The forensic response — capturing evidence about the surround condition before it changes — is equally i...
