3 Terms and definitions

The terms and definitions defined in GB/T 10623 apply to this document.

4 Method overview

Apply a unidirectional compressive force to the specimen in the axial direction. When the specimen is compressed to the specified deformation amount or reaches the specified load or the maximum force value occurs, the test specimen is measured. Actual compressive force, specified non-proportional compressive strength, compressive strength, compressive elastic modulus, upper compressive yield force, compressibility, energy absorption of the rectangular specimen Compression performance indicators such as compression deformation amount and specified force value are used to evaluate the material's ability to resist compression deformation.

5 test conditions

The test temperature is 10℃~35℃.

6 Instruments and Equipment

6.1 Testing machine 6.1.1 The force measuring system of the testing machine is calibrated in the compression direction in accordance with JJG139, JJG475 or JJG1063.The accuracy of the force measuring system of the testing machine is Should reach or better than level 1. 6.1.2 The maximum load required for the test should be within the range of 10% to 90% of the maximum load of the testing machine. ......
