This practice provides a method for evaluating microhardness and microstructure very close (0.002 inch (0.051 mm) or less) to the surface of a disk specimen. Specific accept/reject criteria for partial decarburization ( 3.7.1 ), inadvertent carburization/nitrid
ing (3.7.3), total decarburization/inte
rgranular oxidation ( 3.8 ), and other characteristics evaluated are to be found in the applicable specification where this ARP is referenced.
