GB/T 6609.24-2004 specifies the measurement method of aluminum oxide angle of repose. The standard specifies the determination principle, and the aluminum oxide is naturally deposited to form an angle of repose through a specific device. Detail the required instruments, such as the specifications of the Angle of repose meter. Standardize the collection and preparatory process of the sample to ensure that it is representative. Strictly specify the test operation process, including the material dumping method and the angle Measuring method. With this standard, the aluminum oxide angle of repose can be accurately determined, providing important data for the production, storage and transportation of aluminum oxide, and helping to optimize the relevant process and ensure safety.
