1 ASTM E23-07, “Notched Bar Impact Testing of Metallic Materials,” ASTM International (W. Conshohocken, Pa.), 2007 (originally published 1933). 2 ASTM D6110-10, “Determining the Charpy Impact ...

Charpy testing is a method for determining the relative impact strength of metals. It is also known as the Charpy V notch test. This testing method was developed in the 1940s by S.B. Russell and G.
