This part is part 12 of GB/T 3810.
This part is drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces GB/T 3810.12-2006 "Test methods for ceramic tiles Part 12. Determination of frost resistance". This part with
GB/T 3810.12-2006 compared to the main changes are as follows.
- the formula for calculating the initial water absorption rate E1 (see 5.2, version 5.2 of 5.2);
- modified the temperature requirements (see Chapter 6, Chapter 6 of the.2006 edition);
- modified the final water absorption formula for E2 (see Chapter 6, Chapter 6 of the.2006 edition).
This part uses the translation method equivalent to ISO 10545-12..1995 "Ceramic tiles Part 12. Determination of frost resistance" (English version).
This section makes the following editorial changes.
a) Standard name modified to "Ceramic tile test method Part 12. Determination of frost resistance".

Test method for ceramic tiles
Part 12. determination of frost resistance
1 Scope
This part of GB/T 3810 specifies the test method for all frost resistance of ceramic tiles used in immersion and freezing conditions.
2 principle
After the ceramic tile is saturated with water, it is circulated between 5 ° C and -5 ° C. The surfaces of the bricks should be subjected to at least 100 freeze-thaw cycles.
3 equipment and materials
3.1 Drying box. can work at a temperature of (110 ± 5) ℃; can also be used to obtain the same test results of microwave, infrared or other dry
system.
3.2 Balance. Accurate to 0.01% of sample mass.
3.3 Vacuum device, vacuum after the injection of water to make the water saturation of the device. vacuum pump vacuum can make the device pressure to (60 ± 4) kPa.
3.4 Freezer. can freeze at least 10 bricks, the minimum area of 0.25m2, and make the brick do not contact each other.
3.5 suede.
3.6 Water. The temperature is maintained at (20 ± 5) ° C.
3.7 thermocouple or other suitable temperature measurement device.
4 sample
4.1 samples
The use of not less than 10 pieces of the whole brick, and its minimum area of 0.25m2, for large size of the brick, in order to be able to load the refrigerator,
Cutting, cutting the sample should be as large as possible. Brick should be no cracks, glaze cracks, pinholes, bumps and other defects. If you have to check with defective bricks
In practice, permanent defects were applied before the test, and the defects were checked after the test.
4.2 Preparation of the sample
The bricks were dried in a (110 ± 5) ° C oven (3.1) to constant weight, ie, the difference between two consecutive weighings per hour was less than 0.1%. recording
The quality of each dry brick (m1).
5 soaked in water
5.1 After the brick is cooled to ambient temperature, the brick is placed vertically in the vacuuming device (3.3) so that the brick and the brick and the brick do not come into contact with the inner wall of the device.
