This document specifies a method for determining the ability of metallic wire, of diameter dimension from 0,3 mm to 10,0 mm inclusive, to undergo plastic deformation during reverse torsion. This test is used to detect surface defects, as well as to assess ductility. Working Committee NA 099-00-01 AA "Stahldraht" ("Steel wire") is responsible for German participation at DIN Standards Committee Steel Wire and Wire Products (NAD).
This document replaces DIN ISO 9649:2018-01 .
