GB/T 6286-2021 "Determination of Bulk Density for Molecular Sieves" is applicable to the determination of the loose, tapped, and dry basis bulk density of various granular and powdered molecular sieves. It specifies the test principle, equipment, procedures, and data processing requirements. The core instruments include a 250 mL measuring cylinder conforming to the standard, an electronic balance with a sensitivity of 0.001 g, and a tapping device with a stroke of (3 ± 0.2) mm. Through operations such as pouring and filling, tapping treatment, and precise weighing, the bulk density under different states is calculated, providing technical support for the production, application, and quality control of molecular sieves.
