DIN SPEC 4882:2016-11

The present document has been prepared by Working Committee NA 062-08-24 AA "Elektrische und magnetische Prüfverfahren" ("Electrical and magnetic test methods") at DIN Standards Committee Materials Testing (NMP). The occurrence of grinding burn can be largely avoided by suitable process design. This applies in particular to large-scale damage to the surfaces of the parts. However, due to the many influencing factors during grinding, the occurrence of grinding burn cannot be completely ruled out. Statistically occurring grinding burn is particularly critical in this context, occurring for example as streak-shaped damage transverse to the machining direction. This document specifies the principles for the manufacture and application of reference bodies for the non-destructive testing of grinding burn using electromagnetic methods.
