The ASTM C830-00 (2023) standard specifies a test method for determining the apparent porosity, liquid Absorbance, apparent specific gravity, and volumetric density of refractory materials by vacuum pressure method. These properties are key performance indicators of refractory materials and are widely used as a basis for material selection in product mass evaluation and industrial applications. The standard applies to all refractory shapes except refractory materials that react spiritually with water and minerals. During testing, the specimen is impregnated with liquid under vacuum pressure to ensure complete pore saturation. Data such as apparent porosity, liquid Absorbance, apparent specific gravity, and volumetric density of refractory materials can be obtained through accurate measurement and calculation. These data are of great significance for refractory research and development, quality control and engineering applications.
