Porcelain Enamel Institute (PEI)
Porcelain Enamel Institute (PEI) will tell you where the tile can be installed. The scale ranges between 1 and 5. The lower the number the less foot traffic the tile can handle. These tiles are good for the wall not for under foot. The higher the number the harder and denser the tile. These tiles are good for the floor and can handle heavy foot traffic.
