While the official standard provides exhaustive detail, the general process of ASTM E562-19 can be understood in several key stages:
The standard provides a manual, cost-effective, and statistically sound procedure for estimating the volume fraction of a secondary phase in a multi-phase alloy or material. It relies on stereology—a field of science that interprets three-dimensional structures based on two-dimensional cross-sections. Scope and Applications To implement this methodology legally and accurately in

Operators often default to counting boundary points as a full 1.0 instead of 0.5. Train technicians to strictly apply the half-point rule.
