ActiveRefractory products—Determination of permanent change in dimensions on heating
耐火材料 加热永久线变化试验方法
Application Summary AI generated
This standard specifies the test method for measuring the permanent linear change of refractory products after heating, determining their dimensional stability under high-temperature conditions. It is applied in the quality control and performance evaluation of refractory materials used in industries such as steelmaking, cement, glass, and ceramics, where materials must withstand thermal cycling without excessive expansion or shrinkage. The standard is used by manufacturers and testing laboratories to ensure refractory products meet required specifications for furnace linings, kilns, and other high-temperature industrial equipment.
