ASTM A Standard Test Method for Evaluating the Microstructure of Graphite in Iron Castings. ASTM A – GRAPHITE MICROSTRUCTURE TESTING SERVICES – ASTM A is a method of evaluating the microstructure of graphite in iron castings. The most common gray iron specification will contain Type VII flakes, type A, size , as evaluated in ASTM A Dura-Bar G2 gray iron will contain this type of.
