Determining Average Grain Size

ASTM E112

These test methods cover procedures for estimating and rules for expressing the average grain size of all metals consisting entirely, or principally, of a single phase. The grain size of specimens with two phases, or a phase and a constituent, can be measured using a combination of two methods, a measurement of the volume fraction of the phase and an intercept or planimetric count.

WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM E112 for Determining Average Grain Size. Contact us to learn more.
