Part 2 of GB/T 40380.2-2021 focuses on the determination of Flow velocity of metal powders at high temperatures. This standard clarifies the principle of measuring Flow velocity of powders at high temperatures by using specific funnel outflow characteristics through specific high temperature devices and test procedures. Clarify the technical parameters of instruments required for high temperature furnaces, special funnels, etc. Specify the preparation of metal powder samples before high temperature testing. Key operation steps such as heating procedure, temperature control and powder outflow time measurement are described in detail. It provides a basis for uniform and accurate determination of metal powder Flow velocity at high temperatures. It helps the application research and mass control of metal powders in high temperature processes.
