Izod and Charpy Impact Tester for Molded Plastics

Pendulum impact machine for notched and unnotched Izod and Charpy tests on injection molded plastic bars. Used by molders and compounders to compare toughness of grades and detect brittle parts.

Specification

Standard test bars are molded, notched and broken by a swinging pendulum to read the absorbed energy. Interchangeable hammers cover tough and brittle polymers alike. The unit supports both Izod and Charpy fixtures on one frame.

Features

• Set of pendulums from 1 to 25 J
• Both Izod and Charpy test supports
• Dial or digital energy readout
• Friction and windage correction
• Safety guard with interlock
