GB/T 40380.1-2021 《Metallic powders—Determination of apparent density and flow rate at elevated temperatures—Part 1: Determination of apparent density at elevated temperatures》 Related products

GB/T 40380.1-2021 Part 1 is for the determination of Loose Bulk Density of metal powders at high temperatures. It describes the principle of measuring Loose Bulk Density in a high temperature environment by allowing metal powders to accumulate naturally with a special device. Specify the specifications of high temperature furnaces, specific containers and other instruments to elaborate the preparation process of metal powder samples including collection and pretreatment. Clarifying the operating procedures such as high temperature setting, powder filling and density calculation to provide a unified standard for the accurate determination of metal powder Loose Bulk Density at high temperatures is essential for the development of high temperature processing technology and quality control of metal powders.
