This chamber is commonly used in weld procedure qualification style Charpy programs, and it can typically be set up to condition sub-size Charpy specimens as long as the specimens can be loaded securely and exposed to uniform circulation in the chamber before transfer to the impact tester.

Whether sub-size weld specimens fit cleanly comes down to how you plan to stage them inside the chamber. The key drivers are the sub-size geometry you are using, how the specimens are supported or separated during the soak, and how many you want to condition per cycle without specimens touching each other.

For weld testing, the practical goal is repeatable temperature stabilization and a smooth handoff to the Charpy frame using your lab’s handling approach. The NG-ISCC series is built for controlled sub-zero conditioning ahead of Charpy testing, with model selection based on the temperature target and cooling approach.
