Specialized testing equipment that applies impact to materials and products to evaluate impact resistance and fracture characteristics. Includes Charpy impact testers, Izod impact testers, drop weight impact testers, and pendulum impact testers, used for measuring impact strength of metallic materials, resin materials, and composite materials. Capable of testing in compliance with standards such as JIS K7110 and ASTM D256, essential for quality control and material development in automotive parts, electronic components, and construction materials. Distinguished from tensile testing machines and hardness testers by measuring fracture energy of materials under dynamic loading. Features high-precision measurement capabilities with specimen holders, hammer weight adjustment functions, and digital display devices.
