Reflecting advances in precision measurement technology, ASTM standard E2980, Test Methods for Estimating Average Particle Size of Powders Using Air Permeability, provides way to estimate average size of powder particles. ASTM member Frank J. Venskytis, who claimed usability of this new test method as being able to help control production processes and quality, said uses include processing and QC by powder suppliers and producers of powder-manufactured solid materials.
