GB/T 1482-2010 《Metallic powders - Determination of flow time by means of a calibrated funnel (Hall flowmeter)》 Related products

GB/T 1482-2010 stipulates that the standard funnel method (Hall Flow velocity meter) is used to determine the flowability of metal powders. This standard is based on the principle of free flow of metal powders through the standard funnel of the Hall Flow velocity meter, and clarifies the construction, size and other technical specifications of the Hall Flow velocity meter. The collection and pretreatment requirements of metal powder samples are described, and the operation steps such as sample loading and powder outflow time measurement are standardized. It provides a basis for unified and accurate determination of metal powder flowability, which is of great significance to metal powder mass evaluation and related industrial production.
