Slip Ratings assist when determining whether a tile is suitable for its preferred location in the house, and are developed according to Australian Standards.
It helps identify if a tile is suitable for different indoor areas like bathrooms and kitchens, or outdoor areas like a patio or pool surround.
Pendulum Test
The pendulum test assesses the friction offered by a floor surface when a foot comes into contact with it. It can measure slip potential of both dry, wet and contaminated flooring.
The higher the number, the lower the risk of slipping.
| Pendulum Classification | Slip Risk |
| P0 | Very High |
| P1 | Very High |
| P2 | High |
| P3 | Moderate |
| P4 | Low |
| P5 |
Very Low |
Oil-Wet Ramp Test
The Oil-Wet Ramp test involves laying the tiles on a ramp and applying lubricating oil to the surface of them. Testers walk on the inclined tiles to determine the angle at which they become unsafe. The angle is used to determine the degree of slip resistance.
| Slip Resistance Value | Slip Risk |
| R9 | Very High |
| R10 | High |
| R11 | Moderate |
| R12 | Low |
| R13 | Very Low |
