WebWe 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 \(compliant with both ASTM E23 [1] and ISO 148-2 [2]\) \ and worn anvils \(anvil corner radii and distance outside ASTM tolerances, but within ISO ... WebCharpy is measured on the same test equipment used for Izod impact. Like Izod, Charpy measures impact. In the Izod test, the specimen is clamped vertically, and in the Charpy …
