GB/T 34218-2025 is a special project standard for refractory performance testing, which specifies the test method of high temperature compressive strength. The standard specifies the test principle (measuring the compressire strength of refractory materials in a specified high temperature environment), sample prepative requirements, temperature control parameters, operation steps and result calculation methods, and is suitable for high temperature pressure performance testing of various refractory materials. The standard can unify the industry detection method, ensure the accuracy of data, and provide a reliable technical basis for refractory production quality control, kiln and other high temperature scene application selection and safety performance evaluation.
