The standard goes beyond simple counting by providing standard equations to verify the accuracy of the dataset.

The core principle is elegantly simple and grounded in stereology—the science of inferring three-dimensional properties from two-dimensional sections. When a grid of regularly spaced points is systematically placed over an image of a material's section, the fraction of points that fall on a specific phase provides an unbiased statistical estimate of that phase's volume fraction within the bulk material. Think of it like this: if you randomly throw a handful of tiny pebbles onto a map of a country, the proportion of pebbles that land on forested areas is a good estimate of how much of the country is actually forest. This method is considered superior to other manual methods due to its balance of effort, simplicity, and minimal bias. astm e56219 pdf

ASTM E562-19 outlines a systematic, manual point-counting procedure to accurately estimate the 3D volume fraction of microstructural phases in materials using a 2D grid overlay. The standard enables precise quantification of constituents like ferrite in steels by analyzing microscopic fields and calculating a 95% confidence interval for the result.
