ASTM E562-19e1 is the standard test method for determining the volume fraction of a microstructural constituent by a systematic manual point count. The designation "19e1" indicates that the standard was originally approved or revised in 2019 and has undergone an editorial review (e1) to correct minor typographical or formatting errors without changing its technical substance. The Core Objective

) represents the total volume of a specific phase divided by the total volume of the material. While we live in a three-dimensional world, measuring 3D volumes directly inside an opaque metal is destructive and incredibly difficult. ASTM E562 solves this by using —the science of interpreting 3D structures from 2D cross-sections. Stereological math proves that the point fraction ( Ppcap P sub p astm e562-19e1
