Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 3002-2004 "high temperature refractory refractory strength test method", compared with the GB/T 3002-2004,
The main technical changes are as follows.
--- Reference standard increased GB/T 4513.5, GB/T 4513.6 and GB/T 7321;
--- Increase Note. "For other sizes of the sample, the span can be adjusted accordingly";
--- Removed the provisions of paragraph 5.3.2 and Appendix A of the temperature distribution measurement;
--- Equipment to increase "vernier caliper";
--- Increase "the preparation of shaped products in accordance with GB/T 7321 for";
--- Increase "amorphous refractory preparation in accordance with GB/T 4513.5";
--- Increase "the minimum length of the sample is 100mm, the minimum width and height of 10mm."
--- Increase the "amorphous refractory sample size in accordance with the relevant provisions of GB/T 4513.6 implementation."
This standard uses redrafted Law Amendment uses IS05013.1985 "refractory products high temperature flexural strength test method."

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Flexural strength modulusofrupture
A sample of refractory strip of a certain size, the maximum stress that can be sustained on a three-point bending apparatus.
3.2
Test temperature testtemperature
The temperature at the midpoint of the specimen tension plane (see 5.3).
4 principle
The sample is heated to the test temperature, incubated to a specified temperature profile, and a constant load rate is applied until the sample breaks.
5 device
5.1 loading device
5.1.1 The loading device shall have two lower blades and one upper blade. The three blades shall be parallel to each other. For the standard specimen two support blade
The distance between (125 ± 2) mm. The upper knife edge should be placed in the middle of the two lower knife edge, accurate to ± 2mm (see Figure 1).
Note. For other sizes, the span can be adjusted accordingly.
