Knowledge check

A vendor's nitriding certificate for an H13 forge die lists only 'case depth 0.015 inch, surface 60 HRC.' A second certificate for the same part lists a microhardness traverse with measurement standard, compound layer thickness in microns, Kn setpoints by cycle stage, and a witness coupon ID. Name three of the four levers that determine why these certificates describe different cases, before assuming one of them is wrong.
