TIPS FOR CHARPY IMPACT TESTING MACHINE USE
Test temperature: The temperature of the laboratory for impact testing should generally be within the range of 10~35℃ (that is, the room temperature). For tests with strict requirements, such as the impact test of materials whose toughness is sensitive to temperature changes, the test should be Perform at 20°C ± 2°C. Sample size: Use a measuring tool with a small division value not greater than 0.02mm to measure the width, thickness, and thickness of the notch; use an optical projector [...]
