B0330-Test Methods for Estimating Average Particle Size of Metal Powders and Related Compounds Using Air Permeability

Research report B09-1010 describes the results of an interlaboratory study to determine the precision for B0330 done in five laboratories using tungsten carbide powders in both the as-supplied and laboratory-milled conditions. This report has been published in the absence of any other precision estimates for B0330, despite not having enough laboratories to provide statistically valid results as per ASTM Standard Practice E691.
