The Class G Single-Column Charpy & Izod Impact Tester is purposely designed to minimize the effect of wind resistance during testing, although complete elimination is not feasible. The machine incorporates several features that help reduce aerodynamic interference and ensure accurate, consistent test results.

To address the potential influence of air resistance on the pendulum’s motion, the Class G tester features a pendulum with rounded edges. This design reduces the exposed surface area and helps the pendulum move more smoothly through the air, minimizing disturbances caused by wind resistance.

By reducing wind resistance, the Class G system enhances the reliability of impact energy measurements and ensures that external factors do not compromise test accuracy—especially when precise data is required for critical applications.

However, maintaining a stable and controlled testing environment remains important. It is recommended to conduct tests in a laboratory setting with minimal air movement to achieve the highest level of accuracy and repeatability.
