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.

In an appropriate specification for a specific material where graphite microstructure is an important consideration, this test method may be used as a reference to define concisely the graphite microstructure required.

ASTM A provides images used to classify the form, distribution, and size of the graphite in an iron casting. Need more than one copy?

Good microstructural results require significant preparation to obtain a mirror finish with no scratches or edge rounding prior to etching.
