Tiles are the most common building materials in our modern home decoration. Our common concern for ceramic tiles is their environmental protection and water absorption. But do you know that tiles are also classified? Buy tiles must know the classification of tiles, otherwise you do not know which tiles are suitable for you. Here we introduce: the price level classification tile and tile.
What are the tile classifications?
First, the classification of ceramic tile classification is divided into A, B, C, etc. according to the radioactivity of ceramic tile.
1, A grade
Class A is not limited in scope of use and can be used in all areas of home improvement. Therefore, the environmental performance of indoor floor tiles must meet Class A standards. The national standard for the radioactivity of tiles is GB6566-2001. The radioactive specific activities of natural radionuclides Ra-226, Ru-232, and K-40 in the class A decoration materials satisfy the requirements of IRa ≤ 1.0 and Ir ≤ 1.3 at the same time as class A decoration materials.
2, B level
Class B decoration materials do not meet the requirements of Class A decoration materials but at the same time meet the requirements of IRa ≤ 1.3 and Ir ≤ 1.9 are Class B decoration materials. Class B decoration materials shall not be used for the interior surfaces of Class I civil buildings, but may be used for the exterior surfaces of Class I civil buildings and the interior and exterior finishes of all other buildings.
3, C level
Class C decoration materials do not meet Class A and Class B decoration materials but Class C decoration materials meet the requirements of Ir ≤ 2.8. Class C decoration materials can only be used for exterior finishes of buildings and other outdoor uses. Granite with Ir>2.8 can only be used in places where humans are rarely involved, such as steles, seawalls, and bridge piers.
Second, the grade of tiles is divided into two levels according to the grades specified by national standards:
1ã€Excellent
2, a product
Excellent grades are the best grades, and grade ones are products that have slight flaws. At present, the export volume of ceramic tiles in China is quite large. Basically, every factory has its own products. Some of the products that export orders are also digested in the domestic market.
Third, there is a classification of tiles classified as:
1, A grade
2. Grade B
A grade is the best grade, A grade is divided into AAA grade, AA grade and A grade, AAA grade is the best grade. Grade B products are products that have slight flaws.
