Upon choosing tiles for your residential or commercial project, it is important to consider the slip and wear ratings of the product to make sure that it is suitable for the space. This is very important in terms of safety in foot traffic areas, as well as the performance of the product.
PEI (Porcelain Enamel Institute) rates tiles based on durability and hardness in porcelain and ceramic tiles. The ratings range from PEI 1 to 5 and their details are as follows:
• PEI Class I: Minimal to no foot traffic. These scratch easily, and are recommended for wall use only in residential and commercial properties.
• PEI Class II: Light foot traffic. Suitable for wall and floor applications in bathrooms.
• PEI Class III: Light to moderate foot traffic. Suitable in wall and floor applications in regular traffic areas, including light industrial areas.
• PEI Class IV: Moderate to heavy foot traffic. Appropriate for all residential applications along with light and medium commercial use including work/sales rooms and restaurants.
• PEI Class V: Heavy foot traffic. Suitable for public areas such as shopping centres, airport, and other heavy commercial spaces.
When visiting in stores though, Designer Tile Company’s friendly team members will be able to lead you in the right direction in terms of product usage.
Designer Tile Company uses both the Oil-Wet Ramp Test and the Pendulum Test when measuring the slip resistance of our products.
Oil-Wet Ramp Test
This test is conducted with an individual standing on a ramp at various inclination angles. There are two test methods involved:
1. The individual stands on a water-lubricated ramp barefoot.
2. The operator stands on an oil-lubricated ramp in rubber-soled boots.
The test results from the Oil-Wet Ramp Test are as follows:
• R9: Angle falls between 6° – 10°. Suitable for dry entry lobbies
• R10: Angle falls between 10° – 19°. Suitable for wet entry lobbies.
• R11: Angle falls between 27° – 35°. Suitable for external ramps and most locations.
• R12: Angle falls over 35°. Suitable for most locations.
Slip resistance is measured in the Pendulum Test by assessing the frictional resistance between a rubber slider mounted on a pendulum arm and a wet tile.
Pendulum Test classifications are as follows:
• P0: No location examples available.
• P1: Lift lobbies above entry level.
• P2: No location examples available.
• P3: Shopping centre – food court.
• P4: External walkways.
• P5: External ramps.
