Both methods are used for routine inspections when evaluations are conducted at a single location on the product sample. This test method is not intended to address products which are intentionally carburized to achieve specific results. For example, if an order is placed to test for decarburization and none is found, but the presence of carburization is detected, it shall be reported on the test report that carburization was found.
