HSE-Approved Pendulum Testing for Floor Safety Compliance
Why Is Pendulum Slip Testing Essential for Floor Safety?
Slip accidents cause 171,000 workplace injuries annually in the UK, costing employers £512 million in compensation claims. HSE enforcement notices increasingly cite inadequate floor testing as contributory negligence. Pendulum Test Values provide legally defensible evidence of floor safety compliance. Without documented PTV results, liability exposure remains unlimited.
The pendulum test simulates heel-strike conditions at controlled 2.5kg impact force. Rubber sliders replicate shoe-to-floor contact during walking gait. Results correlate directly to real-world slip probability. PTV 36+ indicates low slip risk, 25-35 moderate risk, below 25 high risk requiring immediate remediation. Our testing follows BS 7976 methodology ensuring court-admissible evidence.
Wet conditions reduce grip by 40-70% compared to dry surfaces. Our testing evaluates both states, identifying floors that appear safe when dry but become dangerous with moisture contamination. Understanding anti-slip ratings helps specify appropriate surface treatments. Testing before and after installation verifies anti-slip coating effectiveness meets requirements.

How Do We Conduct Pendulum Slip Testing?
Calibrated pendulum equipment swings from fixed height, measuring energy loss during rubber-to-floor contact. Five repeat readings at each location ensure statistical reliability. We test minimum 10 locations per 500m², focusing on high-traffic zones, entrances, and contamination-prone areas. Results accuracy reaches 2 PTV units with proper methodology.
Slider selection matches expected footwear conditions. Four-S rubber replicates smooth-soled shoes for commercial environments. TRL slider suits rougher industrial footwear. Water application at 1ml/s flow rate creates standardised wet conditions. Temperature correction factors adjust results to reference 20°C baseline. Each variable follows documented protocols.
Surface roughness measurement via profilometry supplements pendulum results. Rz values correlate to aggregate retention capability. Complete floor testing combines slip assessment with substrate analysis. Our reports cross-reference texture depth to PTV performance, predicting wear-induced slip risk development over service life.
What Do PTV Results and R-Ratings Mean?
Pendulum Test Values directly indicate slip probability. PTV 36-44 provides low risk suitable for most commercial floors. PTV 45-54 achieves moderate safety for wet areas. PTV 55+ delivers high slip resistance for external ramps and heavily contaminated environments. These thresholds derive from 30 years of incident correlation research.
R-ratings measure inclined platform performance with oil contamination. R9 indicates minimal texture for dry areas only. R10 suits occasionally wet zones. R11 provides safety in frequently wet commercial kitchens. R12 handles oily industrial conditions. R13 delivers maximum grip for steep ramps and extreme contamination. Selection depends on specific operational hazards.
Testing existing floors identifies remediation requirements. Adhesion testing verifies substrate suitability for anti-slip treatments. Low PTV surfaces benefit from aggregate broadcasting achieving 15-20 point improvements. Mechanical texturing adds 8-12 PTV points through surface profiling. Our reports specify optimal treatment methods for each floor condition.
HSE Compliance Documentation
Which Industries Require Regular Slip Testing?
Food processing facilities face continual contamination from fats, oils and water. Monthly testing tracks slip resistance degradation between cleaning cycles. Commercial kitchens need quarterly assessments verifying R11 minimum maintenance. Our scheduled testing programmes provide documented compliance history for environmental health inspections.
Healthcare premises require annual slip assessments under HTM 61 guidelines. Hospital corridors, shower rooms and wet areas need specific documentation. Care homes face CQC scrutiny of floor safety evidence. Schools and nurseries benefit from holiday-period testing avoiding operational disruption. Each sector has defined compliance requirements we address.
Retail environments present particular challenges from seasonal contamination variations. Entrance matting effectiveness reduces during heavy footfall periods. Customer areas need testing after refurbishment. Our reports support due diligence demonstrations, reducing slip claim liability. Insurance requirements increasingly mandate documented slip testing evidence.

Frequently Asked Questions
PTV 36 or above indicates low slip risk per HSE guidance. This threshold applies to most commercial and industrial floors. Wet areas benefit from PTV 45+ to maintain safety during contamination. External ramps and high-hazard zones need PTV 55+ for adequate protection. We specify target values based on your specific floor use and contamination risks.
Annual testing satisfies most compliance requirements. High-traffic commercial floors benefit from 6-monthly assessment. Food processing and healthcare need quarterly testing to monitor degradation. After any floor treatment, incident, or refurbishment, immediate re-testing confirms slip resistance. We offer scheduled testing programmes with automatic reminders.
While not explicitly mandated, HSE recognises pendulum testing as the preferred method for slip risk assessment. Courts accept PTV evidence as demonstrating reasonable precaution. Insurance policies increasingly require documented slip testing. Enforcement notices cite lack of testing as negligence. Proactive testing provides essential liability protection.
Post-installation testing verifies anti-slip treatments meet specified performance. We test 7 days after cure completion for accurate results. Comparing before and after values demonstrates improvement. Certification documents coating effectiveness for warranty validation. Re-testing at 12 months confirms durability under service conditions.
Standard surveys covering 10 test locations cost from £350. Larger facilities need additional test points at £25 each. Wet and dry testing at each location provides comprehensive data. Reports include calibration certificates and compliance recommendations. Testing fees credit against remediation quotations when we complete subsequent treatment works.
