Standard Test Methods For Estimating Average Particle Size
May 25, 2016 4.1 These test methods provide procedures for determining the envelope-specific surface area of powders, from which is calculated an average particle diameter, assuming the particles are monosize, smooth surface, nonporous, spherical particles. For this reason, values obtained by these test methods will be reported as an average particle size or Fisher Number.
