We slip test existing floors

and outdoor surfaces in-situ and in laboratory

Grip Doctors test the slip resistance of floors and floor materials according to EN and BS standards using the TRL Pendulum Friction Tester.
We produce detailed reports about floor materials Pendulum Test Values for architects, injury solicitors, surveyors, property managers, floor suppliers, engineers, risk managers and many others.

The pendulum test

The standard for determining slip resistance of floor materials in the Republic of Ireland and the UK is the Transport Road Laboratory (TRL) Pendulum test.

The operations and methodology of using the Pendulum is defined by the British Standard Institute (BSI) in  EN 13036 & BS 7976: 1-3 standard and further developed by the UK Slip Resistance Group (UKSRG) in theirs Guidelines, Issue 5.0 October 2016.

Pendulum Test mimics the way a pedestrian heel makes contact with a floor and measures the dynamic coefficient of friction in dry, wet or contaminated conditions between two materials, the slider and the substrate.

The slider #96 is made of a special 4S rubber (Standard Simulated Shoe Sole) for shod pedestrian traffic. For bare feet pedestrians a softer slider TRRL #55  is used.   

Pendulum Test Values when wet

A minimum of 36 PTV
must be achieved

in dry and wet conditions

Technical Guidance
Document B – Fire Safety

Floors of Escape Routes 1.4.6. The floors of all escape routes (including steps, ramps, and landings) should have non-slippery surfaces.

Technical Guidance
Document M – Access and Use

Access Routes 1.1.3.1 (k) Where an access route is provided the surface should be slip resistant, especially when wet. Guidance on slip resistance is given in Building Regulations 2010 and BS 8300:2009 Annex E.

Technical Guidance
Document M – Access and Use

Access Routes 1.1.3.1. (l) The frictional characteristics of the surface materials used along the access route should be similar to prevent tripping and falling at interfaces between different materials.

Technical Guidance
Document M – Access and Use

Stepped Access Routes 1.1.3.5 (p) Where a stepped access route is provided the surface of the threads should be slip resistant, especially when wet. Guidance on slip resistance is given in BS 8300:2009 Annex E.

You cannot be held liable…

…for a slip and fall injury if your company has certified evidence that your floor meets the HSA requirements of slip resistance.
