The Izod & Charpy Impact Tester is designed to evaluate the impact resistance of plastics, polymers, and composite materials. Using a calibrated pendulum, the tester measures the energy absorbed by a specimen during fracture. This property helps determine toughness, brittleness, durability, and material performance under sudden load.
The tester supports both Izod and Charpy test configurations, making it ideal for laboratories that test a wide range of plastic materials.

❓ FAQs
1. What is the difference between Izod and Charpy tests?
• Izod: specimen clamped vertically
• Charpy: specimen supported horizontally
2. Do I need a notching machine?
Yes—standards require standardized notches for valid impact results.
3. Can this tester measure unnotched samples?
Yes, depending on the selected test mode.
4. What industries use impact testers?
