Steels — Manual point counting method for statistically estimating the volume fraction of a constituent with a point grid

General information

Current stage: 30.20 Effective date: Jan 7, 2023

Originator: ISO

Owner: ISO/TC 17/SC 7

Type: International Standard

Scope

Applies to constituents (a phase as well as a micrographic constituent composed of two or more phases) which are clearly identifiable. The point grid is superimposed a given number of fields of the observed surface. By counting the number of points the volume fraction is calculated.
