Tile slip ratings tell you how much grip a floor tile offers underfoot, measured through standardised laboratory and on-site tests. The three you will meet on UK jobs are the R rating (R9 to R13, shod ramp test), the ABC barefoot class (DIN 51097), and the Pendulum Test Value or PTV, which is the figure the Health and Safety Executive actually relies on. Getting these right is the difference between a floor that passes inspection and one that turns into a compensation claim.<\/span><\/p>

This guide is written for tradesmen specifying and laying floors, and for anyone training into the trade who needs to read a tile datasheet properly. It covers what each rating means, where it comes from, and how to specify slip resistant flooring that holds up under UK regulation. <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Tile slip ratings are classifications that grade a floor surface by its resistance to slipping, usually under wet or contaminated conditions. Because a dry tile rarely causes a slip, the useful numbers are the wet ones. Different tests exist because different environments matter: a factory floor covered in oil behaves differently from a barefoot pool surround, so the industry uses more than one scale.<\/span><\/p>

The point that catches people out is this: no single rating covers every situation. An R rating alone does not clear a barefoot wet area, and a barefoot class tells you nothing about grip in work boots. Always read the datasheet for the test that matches how the floor will actually be used.\u00a0 <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The R rating is the most quoted anti slip rating and comes from the German ramp test, DIN 51130. A tester wearing standardised cleated safety boots<\/a> walks up and down an inclined platform coated with motor oil while the ramp angle increases. The angle at which safe walking stops sets the rating.<\/span><\/p>

The scale runs from R9 to R13, where R9 is the slipperiest and R13 the least. There are no such categories as R1 to R8. The HSE defines each rating by the slip angle recorded on the ramp:<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
