In addition to or instead of the pei rating tiles can be designated as floor or wall tiles based on other criteria.
Ceramic tile wear ratings.
Pei ratings are only used for glazed ceramic tiles.
The chart below explains the wear rating system.
How does a p1 rate against the pei wear rating.
Glazed and unglazed tiles are rated for scratch resistance and hardness via the mohs scratch test.
We are looking at different wood look porcelain tiles.

The pei rating applies only to glazed tiles.
Thanks for reaching out to us.
Tile designated for installation on a wall receives no foot traffic and in fact almost no wear of any kind.
The porcelain enamel institute pei rates ceramic tiles for wear on a scale from 1 to 5.
The wear rating explains how easily abrasions may show on glazed tile.
This rating does not measure the overall quality of the tile but the tile s resistance to abrasion and ability to handle foot traffic.
Often this is referred to on technical specifications as abrasion resistance durability classification or pei rating.
As such this tile can be thinner and smoother since safety is not a concern.
Most of them have a wear rating of 5 but the one we like has a rating of p1.
Darker tiles may wear more easily than lighter ones.
It s a scale of 0 5 that indicates how a floor tile will wear due to the amount of foot traffic and therefore suggest what floor applications if any that the tile is appropriate for.
