What is ceramic tile pei rating.

Pei porcelain enamel institute ratings help you determine the hardness and durability of tile. In many cases some of the most beautiful and costly tiles have a pei 1 or 2 rating. The pei rating applies only to glazed tiles. This hardness is determined by the manufacturer using a standardized test.

It does not measure the fracture strength of the entire tile nor does it offer any rating of the slip resistance of the tile. This is crucial because not all tile can be used in all areas. A pei rating is given to a tile product based the hardness of its glaze. A rating of 1 means the tile can be used on very light wear areas and should only be installed in rooms where people use soft footwear such as sneakers or slipper.

The tiles are rated from a soft 1 or talc to 10. Tile with this rating is not suitable for installation on floors. It is important to note that the pei rating is the result of testing glaze wear only and not slip resistance. Tile that experiences much foot traffic should be harder and denser than than that receives no foot.
