1 Scope
This document specifies a point counting method for statistically estimating the volume
fraction of a constituent through the microstructure of a steel by means of a point
grid.
It applies to constituents which are clearly identifiable.
By default, counting is performed manually, but can be computer assisted or substituted
by validated computer algorithms.
NOTE In this document, the word "constituent" can designate a phase as well as a micrographic
constituent composed of two or more phases.
