The Class H Charpy impact tester is built around the main international standards used for metallic impact testing. It supports Charpy testing in line with ASTM E23, which is the core reference for many metal producers and labs. On top of that, it can be used for fracture-toughness related testing according to ASTM E1820 and instrumented impact work per ASTM E2298 when the instrumented configuration is installed.

For labs that work under European or mixed standards, the system also supports ISO 148 and EN 10045 Charpy requirements. Energy measurement hardware can be calibrated against ASTM E74 Class AA procedures for high-level accuracy.

Because the frame, pendulum, striker geometry and support span are all specified with these documents in mind, labs can qualify procedures, run routine QA work and support certification testing without redesigning their methods around the machine.
