ASTM E562-19e1 is the standard for determining microstructural volume fraction via manual point counting, offering reliable results without complex software. While considered a foundational, high-accuracy tool, it is often critiqued for being subjective, labor-intensive, and prone to errors exceeding 10% compared to automated methods like ASTM E1245.

The core methodology of ASTM E562 is deceptively simple yet mathematically robust. It involves superimposing a grid of points (typically a clear plastic overlay or a digital reticle) onto a metallographic specimen viewed through a microscope.
