This part is part 10 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 3810.10-2006 "Test methods for ceramic tiles Part 10. Determination of wet expansion".

This section is the main change compared with GB/T 3810.10-2006 as follows.

- modified terms and definitions (see Chapter 2, Chapter 2 of the 2006 edition);

- modified the formula for wet expansion (see Chapter 7, Chapter 7 of the 2006 edition).

This part uses the translation method equivalent to ISO 10545-10.:1995 "Ceramic tiles Part 10. Determination of wet expansion" (English version).

This section makes the following editorial changes.

--- Standard name changed to "Ceramic tile test method Part 10. Determination of wet expansion".

This section is proposed by the China Building Materials Federation.

This part of the National Building Sanitary Ceramics Standardization Technical Committee (SAC/TC249) centralized.

1 Scope

This part of GB/T 3810 specifies the test method for the wet expansion of ceramic tiles.

2 Terms and definitions

The following terms and definitions apply to this document.

Wet expansion

The bread is immersed in boiling water to heat the expansion to accelerate the expansion ratio.

3 Principle

By heating the bricks into boiling water to accelerate the wet expansion, the length change ratio is determined.

4 Equipment

4.1 measuring device, dial gauge with a dial gauge or similar device, accurate to 0.01mm.

4.2 nickel steel (nickel iron alloy) standard block, length and sample length is similar to the use of insulation fixture.

4.3 Roasting furnace, can be 150 °C/h heating rate rose to 600 °C, and the control temperature deviation of not more than ± 15 °C.

4.4 vernier caliper, or other suitable device for length measurement, accurate to 0.5mm.

4.5 Boiling device to keep the test sample in boiling deionized water or distilled water for 24 h.

5 Samples

The specimen consists of 5 pieces of the whole brick. If the measuring device is not long, the specimen shall be cut from the center of each brick. The minimum length shall be 100mm, the minimum width of 35mm, the thickness of the thickness of the brick.

For extruded bricks, the length of the specimen should be along the extrusion direction.

Prepare the sample according to the requirements of the measuring device (4.1).
