Understanding ASTM E562-19e1: Standard Test Method for Point Counting by Random Manual Point Counting

Published by ASTM International, this standard provides a rigorous, repeatable procedure for estimating the volume fraction of a constituent phase or feature within a two-dimensional polished section. This article dissects the standard in detail, covering its scope, history (including the meaning of the -19e1 suffix), theoretical basis, required apparatus, step-by-step procedure, calculations, and practical applications. astm e562-19e1
