Slip resistance of flooring and floor coatings

Standard BS EN 8204 -2 says to test the slip resistance as per BS 7976-2 and the result of the slip resistance value [PTV (pendulum test value)] of the floor surface is not less than 40.

When flooring / coatings are wet, the slip resistance depends on the depth of the surface micro-texture. The smoother the surface, the lower the slip resistance. Slip resistance is only retained if the floor is cleaned correctly by regular washing and cleaning with suitable cleaning products and techniques. Generally, the more slip resistant the floor when wet, the more difficult it is to clean. Existing floor surfaces that have become slippery despite cleaning may be roughened by mechanical treatment, e.g. shot-blasting the surface. Alternatively, a resin coating containing hard angular granules of natural or synthetic material may be applied to a cleaned and textured floor surface to increase slip resistance.

Testing can be conducted in 2 different methods:

Standard BS EN 8204 -2 says to test the slip resistance by roller coaster method and convert the readings to PVT values and the result of the slip resistance value [PTV (pendulum test value)] of the floor surface is not less than 40.

Determination of slip resistance of pedestrian surfaces by the ramp/trolley method, alternatively known as the roller coaster method:

The device consists of a trolley having four wheels and a slider, together with a ramp. The trolley is given an initial velocity by running down the ramp under the action of gravity. The trolley then runs across the floor area to be tested. The friction generated by the slider traversing the floor causes the trolley to come to rest. The dynamic coefficient of friction is calculated from the distance it takes for the trolley to come to rest.

The device is used to determine the slip resistance of a floor surface by measuring the dynamic coefficient of friction. It might be used, particularly by floor end users, to detect changes in the dynamic coefficient of friction caused by contamination or wear of the floor surface and/or changes caused by the method of cleaning the floor.

The reading shall be more than 130.

Pendulum test for slip:

Standard BS EN 8204 -2 says to test the slip resistance as per BS 7976-2 and the result of the slip resistance value [PTV (pendulum test value)] of the floor surface is not less than 40.

Let see the Pendulum test:

The reading shall be more than 40.
