PTV Ratings explained
Briefly, PTV numbers indicate how slippery a tile is – the higher the number, the less likely it is for someone to slip. For a more detailed explanation, read on.
Similar to “R” ratings, the PTV (Pendulum Test Value) is intended to give a measure of the tendency to slip on a tile.
Values above 35 are classified as a low risk of slip.
Values from 25 to 35 inclusive are classified as a moderate risk of slip.
Values below 25 are classified as a high risk of slip.
