How to divide the tiles?

Answer:

The state of the ceramic tile by the tile level is divided into A, B, C and so on. 1, A level. Class A use of the scope of unlimited, can be used in various places of home decoration. So the environmental performance of indoor tiles must meet Class A standards. The standard for the use of tiles for radioactive use is GB6566-2001. Class A decoration materials in the natural radionuclide radium radium-266, thorium-232, potassium-40 radioactive specific activity at the same time to meet the IRa ≤ 1.0 and Ir ≤ 1.3 requirements for the A class of decoration materials. 2, B grade. Class B decoration materials do not meet the requirements of Class A decoration materials but at the same time to meet the requirements of IRa ≤ 1.3 and Ir ≤ 1.9 for the B class decoration materials. Class B decoration materials can not be used for the interior of Class I civil construction, but can be used for the outer surface of Class I civil construction and the interior and exterior of all other buildings. 3, C level. Class C decoration materials do not meet the A, B class decoration materials requirements but meet the Ir ≤ 2.8 requirements for the C class decoration materials. Class C decoration materials can only be used for exterior finishes and outdoor use. Ir> 2.8 granite can only be used for monsters, seawalls, piers and other human rarely involved. According to the national standard level, tiles can be divided into two levels: 1, A grade goods A grade is the best grade, A grade is divided into AAA level, AA level and A level, AAA level is the best level. 2, B grade goods Class B products are slightly flawed products. Whether it is tiles according to the radioactive or standard provisions of the tile, we can find different tiles or have their own different nature.
Tiles are the country according to the radio of the tiles are divided into A, B, C and so on. Class A use of the scope of unlimited, can be used in various places of home decoration. Class B decoration materials can not be used for the interior of Class I civil construction, but can be used for the outer surface of Class I civil construction and the interior and exterior of all other buildings. Class C decoration materials can only be used for exterior finishes and outdoor use. The tiles are divided into two levels according to the national standard: 1, excellent products 2, a product Or tile classification is classified as: 1, A grade goods 2, B grade goods
Excellence: no obvious flaws, no broken, no missing angle, after the color difference after no significant color First grade: there is a certain pinhole, there are flaws, but not more than a certain number, there are some missing angle and cracks, but the distance is not large (each type of implementation of different standards, the details can be seen on the carton standards, To obtain a test report to know, the general Atlas also comes with)
