The threaded section will give evidence of carburization if the average of the four readings indicates a positive value. This test method is not intended to address products which are intentionally carburized to achieve specific results. If the document is revised or amended, you will be notified by email.
The microindentation method 2 shall be considered the referee method. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.

Monitoring Standards monitoring is a free service designed for adtm who wish to be alerted of changes to or new editions of the standards required in your work. 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. Therefore, limits have been established for three different product groups: Already Subscribed to this document.
