The underlying principle of ASTM E562-19 is straightforward: the areal fraction of a phase on a polished, two-dimensional section is directly proportional to its three-dimensional volume fraction. 1. Specimen Preparation

The method uses statistics to determine the volume fraction based on how many points fall within the phase of interest.

It provides a systematic, unbiased way to quantify phases, superior to many other manual techniques, especially in terms of effort and accuracy. astm e56219 pdf

To determine the volume fraction of an identifiable constituent (e.g., ferrite, austenite, inclusions) in a microstructure.

: Success depends on high-quality specimen preparation; phases must be clearly distinguishable under the microscope. The underlying principle of ASTM E562-19 is straightforward:
