This standard specifies a unified method for determining the bulk density of granular refractory materials with particle sizes larger than 2.0 mm. It describes two main test methods: the weighing method and the burette method, with the weighing method designated as the arbitration method. This method is suitable for evaluating the compactness and internal structure of refractory raw materials. The test typically requires the use of a high-precision analytical balance and a specialized bulk density tester, which often operates based on the Archimedes buoyancy principle and may include a vacuum saturation device to accurately measure the dry weight, saturated weight, and buoyant weight of the sample in immersion liquid, thereby calculating the bulk density.
