The Class D Single-Column Charpy Impact Tester operates with a striker velocity of 5.24 m/s. This is the speed at which the pendulum impacts the specimen during testing and is a critical factor in determining the energy absorbed upon fracture.

Maintaining a constant velocity of 5.24 m/s ensures repeatable and standardized testing conditions in accordance with Charpy testing protocols. This consistent velocity is essential for obtaining accurate and reliable impact energy readings.

The selected striker speed supports compliance with international testing standards and helps assess a material’s resistance to sudden impact loads. It enables clear comparisons between different materials, making it useful for quality control, design validation, and research.
