ASTM Grain Size/Nodularity Analysis Standard
Based on the IAM-1 Morphometric Image Analysis above, the IAM-MET is a multi-morphology calibration standard designed specifically for ASTM. The IAM-MET includes all plates as found in IAM-1 except for plate 4, which is pictured above. This plate contains 9 images of irregular shapes, simulating features commonly found in metallurgical applications. As required by the ASTM standard, the IAM-MET includes secondary certification of plates 1, 2 and 8.
