PEI Rating
The PEI rating is a standardized measure of how well a glazed tile can fight surface wear caused by foot traffic. It is measured by conducting controlled laboratory tests that evaluates how a particular glazed surface performs under repeated abrasion. This makes tile PEI rating an important factor to consider while choosing tiles.
Also known as ceramic tile PEI rating, the measure is used to check how well a tile can hold its look.
How the PEI Rating System Works?
The PEI system is an abrasion resistance classification that is measured and established through an abrasion testing standard. The classification is based on a PEI scale 1-5 where each level stands for a particular floor traffic rating or the degree of surface wear resistance.
| PEI Rating | Traffic Level | Typical Use | Selection Guidance |
|---|---|---|---|
| PEI 1 | Very light | Wall tiles, decorative surfaces | Not suitable for floor tile; use only where there is no foot traffic |
| PEI 2 | Light | Bathrooms, low-use residential areas | Suitable for areas with occasional barefoot or soft footwear use |
| PEI 3 | Moderate | Residential flooring (bedrooms, living rooms) | Good for general home use with normal foot traffic and limited abrasion |
| PEI 4 | Medium–heavy | Kitchens, hallways, entryways, light commercial | Recommended for high-use residential areas and moderate commercial spaces |
| PEI 5 | Heavy | Commercial spaces, public buildings, high-traffic zones | Best choice for constant foot traffic and environments with abrasive conditions |
As the rating increases, so does the tile's ability to withstand abrasion, making it more suitable for demanding conditions.
What the PEI Rating Indicates?
The PEI rating is more or less focused on the visual longevity and surface durability of a tile. It is closely related to tile scratch resistance rating. Major characteristics include:
- Shows how well a particular tile surface resists dulling, scuffing, and abrasion.
- Defines the traffic performance classification of a tile based on its expected usage.
- Denotes how well a tile can maintain its appearance rather than structural strength.
It is important to note that this rating applies primarily to glazed surfaces and does not measure properties such as impact resistance or load-bearing capacity.
