Effects of Removing and Replacing an 8-MM Charpy Striker on Absorbed Energy

CODEN: JAIOAD

Abstract

It has been thought that removing and replacing an in-tolerance 8-mm striker may affect the results of a Charpy test. This thought brought about a requirement in Standard Test Method E23 [1] that states that if a striker is removed and replaced on a Charpy machine, the indirect verification is void and a new verification test must be performed. Groups of NIST SRM 2092 and SRM 2096 specimens were tested on machines with three different striker-mounting designs. The specimens were tested with the striker removed and replaced between groups. The results of these tests support a change in the standard that can make removing and replacing the striker acceptable without performing a new indirect verification test.
