PEI (Porcelain Enamel Institute) ratings help you determine the hardness and durability of the tile. This is crucial because not all tile can be used in all areas. PEI ratings act as a kind of shortcut to figure out where the tile can be installed.
From this scale you can see the numbers of revolutions required in the testing method to abrade the tile.
