GB/T 5073-2022 specifies the compression creep test method for dense shaped and shaped insulating refractory products, detailing the test principle, specimen requirements, operating procedures, and result calculation. It is applicable to the determination of compression creep properties of such products at temperatures up to 1600°C. The core of the standard lies in evaluating the structural stability of refractory materials under long-term service by monitoring their deformation behavior under constant pressure at high temperatures, thereby supporting furnace design and material selection. The test requires a compression creep testing machine that meets the requirements, precise temperature control devices, and temperature measurement instruments such as thermocouples that comply with the standard specifications. This ensures the accuracy of temperature and pressure control, providing a unified technical basis for quality inspection and performance evaluation of refractory materials.
