GB/T 1431 - 2009 specifies the method for determining the compressive strength of carbon materials. This standard specifies the technical parameter requirements of test equipment, such as Pressure Tester, and specifies the preparation process of the sample, including size and shape specifications. During the test, the sample is applied to the specified rate until it is destroyed, the data is recorded and the compressive strength is calculated. Compressive strength is a key indicator to measure the performance of carbon materials and affects its application in many fields. Through this standard, the compressive capacity of carbon materials can be accurately determined, providing a strong basis for manufacturers to control product mass and scientific research institutions to carry out material research.
