This standard BS EN 14231:2003 Natural stone test methods. Determination of the slip resistance by means of the pendulum tester is classified in these ICS categories:
91.100.15 Mineral materials and products
91.060.30 Ceilings. Floors. Stairs
This European Standard specifies a test method to determine the slip resistance value of the surface of the exposed face of natural stone elements intended to be used for flooring in buildings. NOTE 1 If the surface of the exposed face has a roughness measured according to prEN 13373 higher than 1 mm it will be considered as not slippery, without performing the test. NOTE 2 This method can be used for laboratory measurements or on floors in service.
