We provide slip resistance values for all of our floor tile ranges. The methods used to measure slip resistance vary from country to country. The UK HSE recommends the British Pendulum Test whereas the most of Europe favours the DIN Ramp test. The current Health and Safety Executive recommendation is to combine the Pendulum test with a measurement taken by a surface micro-roughness meter.
BS7976 UK Pendulum Test
The UK Pendulum test consists of an apparatus with a swinging arm that passes over the surface of the tile to measure the friction / resistant encountered. The test is divided into two separate areas using different hardness of rubber sliders to differentiate between shoe (96) and barefoot (55) traffic. A value (co-efficient of friction) of 36 and above is described as a low slip risk for public wet areas by the Health and Safety Executive.
DIN51097 Barefoot Ramp Test
This is as it says for wet barefoot areas only and is measured in values of A to C. A is suitable for mainly water splash areas for example changing rooms, B is for pool surrounds, shower areas etc and C is for walk through pools, ramps into pools etc.
DIN51130 Shod Foot Ramp Test
This is for wet shoe trafficked areas only. Tiles are measured in two ways, an R value and a V value. The R measures the incline suitability and the V measures the volume of water / matter etc that can pass under the shoe without causing a slip (like stud face tiles etc).
Surface Micro-roughness Test
This is used to simply measure the roughness of the surface to give an idea of how slippery it would be in water-contaminated areas. The acceptable roughness varies according to what contaminant is likely to be encountered, but it is generally recognised as being low risk over a value of 20 for tiles.
