Low Energy Plastic Impact Testers

The Model IT503 plastics impact tester, together with the Model IT504, continue to set the industry standard for versatility, ease of operation and display of information with high resolution.

These machines are capable of determining the impact resistance using either a Charpy or Izod configuration, without changing the entire pendulum. The user attaches the appropriate striking tup on the pendulum and the specimen clamp or anvils in the base of the unit to test plastics in accordance with ASTM D256 (Izod impact), ISO 179 (Charpy impact), ISO 180 (Izod impact), ASTM D6110 (Charpy impact), ASTM D4812 (Unnotched Cantilever Beam impact), ASTM D4508 (Chip impact), ASTM D950 (Adhesive Bond impact) and other similar standards.

The aerodynamically designed compound pendulum provides maximum rigidity in the direction of the impact and virtually eliminates any windage losses. Pendulum capacity is easily changed by adding on any one of the seven optional weight sets.
