The Class D Single-Column Charpy Impact Tester is designed to minimize the effects of wind resistance during testing, supporting consistent and accurate impact energy measurements.

To reduce aerodynamic interference, the tester features a pendulum with a streamlined profile and rounded edges. This design decreases the surface area exposed to airflow, allowing the pendulum to move through the air with reduced drag.

While it is not possible to eliminate wind resistance entirely, the machine’s engineering significantly limits its impact. For optimal accuracy, it is still recommended to perform tests in a controlled environment with minimal ambient air movement.
