R11? A+B+C? When choosing a tile, slip resistance is important to consider, but without prior knowledge the various systems used can be confusing. Take a look at this post to find out what it all means.
THE “R” RATING
The “R” rating system refers to “ramp test” and is used to test the slip resistance of a tile at various inclines. This test is performed in safety footwear with oil lubrication. The “R” value of a tile can range from R9 – R13 with R13 being the most resistant.
R9 – Slip resistance on a 3-10 degree incline
R10 – Slip resistance on a 11-19 degree incline
R11 – Slip resistance on a 20-27 degree incline
R12 – Slip resistance on a 28 – 35 degree incline
R13 – Slip resistance on a 36 degree incline and above
THE “ABC” RATING
The “ABC” rating system is based upon barefoot use, so should primarily be considered when tiles are going to be used in wet areas or any other place where footwear would not be worn. This test is performed barefoot with soap-like lubrication. There are three possible ratings “A”, “B”, and “C” with “C” being the most resistant.
|Group C (A+B+C)||R13||Group C, R13:
Strongest level of slip resistance available. Best used in commercial wet areas with heavy footfall e.g public swimming pools
|Group B (A+B)||R11, R12||Group B, R11 & R12:
Ideal for use in areas where the floor is something wet such as bathrooms, kitchens and outdoor patios.
|Group A||R9, R10||Group A, R9 & R10:
Lowest level of available slip resistance. Suitable for use in most indoor areas like living rooms, kitchens and hallways.
