What is porcelain tile pei rating.

Pei ratings act as a kind of shortcut to figure out where the tile can be installed.
Porcelain tile can be used in residential and commercial properties on a variety of surfaces.
The results of this test will determine the proper usage of a product.
The pei rating is essentially a measurement of the surface enamel s resistance to abrasion.
Tile that experiences much foot traffic should be harder and denser than than that receives no foot traffic.

This hardness is determined by the manufacturer using a standardized test.
Pei is the abbreviation for porcelain enamel institute.
It is commonly used on walls and shower surrounds on counter tops and on floors.
The pei or porcelain enamel institute has established a rating scale that helps consumers determine the durability and hardness of different types of tile.
The pei rating class begins with a 0 rating which is best suited for light duty applications in homes.
It is measured by the use of a machine known as a rotary abrasion resistance testing machine in which steel ball bearings are pressed down and rolled over the surface of the tile while an observer watches the effect.
The best type of tile would be a full body darker porcelain tile with a pei rating of 4 or 5.
