GB/T 41329-2022 《Determination of flow rate of metallic powders—Calibrated funnel method (Gustavsson flowmeter)》 Related products

GB/T 41329-2022 provides for the determination of metal powder flowability by standard funnel method (Gustaveson Flow velocity meter). It is based on the principle of metal powder flowing out through a specific standard funnel, specifies the specifications of instruments such as Gustaveson Flow velocity meter, and details the preparation steps of metal powder samples, covering powder collection, pretreatment, etc. Standardize the determination operation, including funnel installation, powder filling method, and the process of accurate powder outflow time measurement. The standard provides a unified specification for the determination of metal powder flowability, which helps metal powder quality control and promotes the development of related powder metallurgy industries.
