ASTM E 112 grain size measurements are performed. Results are cumulated for automated statistics and graph generation. Final results can be printed directly from Clemex Vision. Raw data are linked to their respective objects and can be exported in Excel format. No difficulties were encountered in analyzing grains without twins. Twinned grains were analyzed using a semi-automatic process based on the Heyn method.
