Assessing the impact toughness of non-metallic materials is necessary to ensure durability and performance, and our impact testers (available in models CJS-5J/50J) offer a reliable solution for that purpose. Engineered to meet international standards like ISO179 and GB/T1043, it handles both notched and unnotched samples with ease. Whether your samples are machined or injection-molded, the Charpy impact testing machine delivers fast, precise, and repeatable results, all thanks to its intuitive pointer-based design. Additionally, customizable pendulums are available, allowing for flexibility in impact energy testing.
