GB/T 31057.3-2018 "Particulate materials—Determination of physical properties—Part 3: Measurement of flowability index": This standard is part of a series of standards for testing the physical properties of particulate materials. It specifies the definitions of terms, measuring instruments, and test methods for the flowability index, applicable to powder materials with an average particle size ranging from 5 μm to 5 mm. The test requires comprehensive consideration of parameters such as the angle of repose, compressibility, and spatula angle. For some samples, the degree of aggregation or uniformity must also be calculated. The standardized process ensures the scientific and consistent evaluation of the flowability of particulate materials.
