GB/T 5071-2013 "Refractory materials — Test method for true density" specifies the test method for determining the true density of dense refractory materials using the liquid displacement method (commonly using kerosene). By measuring the volume of the immersion liquid displaced by a sample of known mass, the mass per unit volume of the solid portion of the material, excluding pore volume, is calculated. This serves as a fundamental physical property indicator for refractory raw materials and products.
