For tiles where people regularly walk barefoot, an additional anti-slip value applies.
This barefoot slip resistance value is expressed in three letters: A, B & C.
A stands for a non-slip value for dry floors, such as a dry dressing room floor.
Slopes > 12°
B indicates that the anti-slip rating is high enough for wet floors, such as showers in commercial areas.
Slopes > 18°
C stands for damp or soaking wet floors in, for example, swimming pools, such as walk-through foot baths or stairs in the water.
Slopes > 24°
The values R9 and R10 also almost always have the addition A, so they can be used perfectly for the bathroom in your home. Would you like to know more about the anti-slip value and how it is determined? Read more about the anti-slip value of shoes.
