Slip Ratings Explained

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.

COVID-19 Update

We recently added some new tiles to the showroom, one in particular being the St Pierre tile. Please read this post to see our approach to the Coronavirus situation. It’s safe to say right now we’re collectively facing a time of unprecedented uncertainty. At the heart of Just Tiles, we are a family business and … Read more
