How Is Slip Resistance Measured?
When choosing slip-resistant floor tiles, you may come across R ratings and Pendulum Test Values (PTV). Both are used to indicate how slip resistant a floor surface is and can help determine whether a tile is suitable for a bathroom.
R Ratings
R rated tiles range from R9 to R13, with higher ratings indicating greater slip resistance. R10 and R11 tiles are commonly considered the most suitable for areas where floors may become wet.
PTV Values
A Pendulum Test Value (PTV) is another measure of slip resistance, with a wet PTV of 36 or above generally considered to represent a low slip risk value.
