In most cases, information about its characteristics is included on the packaging of tiles and ceramics
which is very important to pay attention to when buying
This information includes:
quality grade
PEI wear grade
WA water absorption rate
Coefficient of friction COF
Cold resistance
Multicolor
The features of good ceramic tile
1 - The quality of ceramic tile
The first and most important parameter that we examine is the quality level of ceramics
Ceramics are placed in 4 categories in terms of quality
which are known as grade 1 to grade 4 ceramics
The lower the quality level, the higher the quality of ceramic tiles
According to this criterion, you can choose the right ceramic for any place
The suitable ceramic for the floor should be grade 1 or at least grade 2
But the walls can be made of grade 3 ceramic tiles
2 - PEI's abrasion grade
PEI stands for Porcelain and Enamel Institute, which means wear degree
The degree of abrasion shows the durability of the ceramic as a floor ceramic
This index is only for glossy ceramics and is not present in matte ceramics
And the higher the amount of PEI, the greater the wear resistance of ceramic tiles
Suitable for Grade III and IV PEI homes and residential spaces
But in commercial spaces, it is suitable for their PEI grade to be V
3 - The degree of absorption of ceramic tile water WA
The degree of water absorption or WA is another important classification to consider
WA stands for Water Absorption and means the amount of water absorption in ceramic tiles
Using this criterion, it is possible to choose ceramic tiles suitable for wet areas as well as outdoor spaces
According to this grading, ceramic tiles are divided into 4 categories
1- Tiles and ceramics that absorb 7% of their weight, such as non-glass tiles
2- Tiles and ceramics that absorb water between 3 and 7% of their weight, such as semi-glass tiles
3- Tiles and ceramics that absorb water between 0.5 and 7% of their weight, such as glass tiles
4- Tiles and ceramics that absorb water between 0 and 0.5% of their weight, which are impermeable tiles and ceramics.
Like Chinese ceramic tiles
4 - Tile friction coefficient
Lisi level of ceramic tiles or coefficient of friction indicated by COF
COF stands for Coefficient of Friction
which expresses the resistance of ceramic tiles against slipping
The higher this amount, the greater the resistance of ceramic tiles against slipping
And the lower this amount is, the resistance of ceramic tiles to slipping is lower, which means the floor is more slippery
As a result, cof above 50 is suitable for residential spaces
And cof above 6 is suitable for commercial use

5 - Resistance to cold and freezing
This index is mostly used for tiles and ceramics that are supposed to be used outdoors
which shows the resistance of ceramic or tile against cold
6 - Multi -color
Multicolor refers to tiles and ceramics with various colors
And it is suitable for people who want tiles and ceramics that are arranged together to have a variety of colors
And each of them has a unique color
