We investigated the influence of the state of wear of Charpy machine anvils on test results by performing impact tests on NIST specimens of three energy levels with a machine equipped with new anvils (compliant with both ASTM E23 and ISO 148-2) and worn anvils (anvil corner radii and distance outside ASTM tolerances, but within ISO tolerances).
