This part is part 9 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 3810.9-2006 "Test methods for ceramic tiles Part 9. Determination of thermal shock resistance".

This section is the main change compared with GB/T 3810.9-2006 as follows.

- modified the requirements for low temperature sinks (see 4.1, version 4.1 of 4.1);

- modified the requirements for the sample (see Chapter 5, Chapter 5 of the 2006 edition);

--- modified the test time requirements (see 6.4, 2006 version 6.4);

--- modified the test procedure (see 6.4, 6.5, 2006 6.4).

This part uses the translation method equivalent to ISO 10545-9.:2013 "Ceramic tiles Part 9. Determination of thermal shock resistance" (English version).

In this part of the normative reference to the international documents have a consistent correspondence between the following documents.

Test methods for ceramic tiles GB/T 3810.3-2016 Test methods for ceramic tiles - Part 3. Water absorption, apparent porosity, apparent relative density and bulk density (ISO 10545-3.:1995, IDT).

This section makes the following editorial changes.

--- Standard name changed to "Ceramic tile test method Part 9. Determination of thermal shock resistance".

This section is proposed by the China Building Materials Federation.

1 Scope

This part of GB/T 3810 specifies the test method for thermal shock resistance of various types of ceramic tiles under normal conditions of use.

Unless otherwise approved, different test methods (submerged or non-submerged tests) should be used depending on the water absorption.

2 Normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document.

3 Principle

The thermal shock resistance of the whole brick was measured by 10 cycles of the sample between 15 ° C and 145 ° C.

4 Equipment

5 Samples

Specimens should be randomly selected from the sample and tested with at least 5 pieces of the entire brick.

Note. For large bricks (ie, bricks longer than 400mm), it is necessary to cut, cut as large as possible, the center should be consistent with the original center. in in case of doubt, use the whole brick to be accurate with the result of the cut brick.
