Charpy & Izod Pendulum Impact Tester for Plastics
Precision Impact Testing for Plastics, Polymers, Composites & Thermoplastic Pipes
The Charpy & Izod Pendulum Impact Tester for Plastics is a precision laboratory instrument engineered to evaluate the impact resistance, toughness, and brittleness of polymer materials by measuring the energy absorbed during fracture. Operating on the time-tested energy-conversion principle, a calibrated pendulum hammer is released from a fixed height to strike a notched or unnotched specimen, and the difference between the pendulum's initial and post-impact energy reveals the material's true impact strength.
The Torontech family of plastics impact testers supports both the Izod method (vertical cantilever-beam specimen) and the Charpy method (horizontal simply-supported specimen) through interchangeable hammers, vises, and positioning fixtures. Every machine in the range is engineered for repeatability, with high-precision bearings, low-friction pendulum systems, shaftless photoelectric or rotary encoders for angle measurement, and integrated software that automatically compensates for energy losses caused by air resistance and bearing friction.
From compact, economical entry-level units rated at 5J for routine quality-control labs, up to fully-featured 50J multi-hammer systems and specialized ISO 9854-compliant testers for thermoplastic pipes, the Torontech impact tester portfolio is built to comply with the world's most demanding test standards ASTM D256, ASTM D6110, ISO 179, ISO 180, and ISO 9854 making every result globally recognized and audit-ready.
