The Izod Impact Tester measures the energy absorbed when a notched specimen is fractured by a pendulum strike, a key measure of impact resistance and toughness for plastics and other rigid materials.

Our engineering team typically responds within 24 hours.
The Izod Impact Tester is a laboratory testing instrument designed to evaluate the impact resistance and toughness of plastics and other rigid materials. A notched specimen is held as a vertical cantilever and struck by a swinging pendulum, and the energy absorbed in breaking the specimen is measured to assess how the material behaves under sudden impact.

The tester is used to evaluate the impact strength and notch sensitivity of thermoplastic and thermoset materials, and to compare the toughness of different polymer grades.
It supports impact evaluation of reinforced plastics, filled compounds, and other rigid engineering materials where resistance to sudden loading is important.
The instrument can be used to assess molded plastic parts, housings, and enclosures that may be exposed to impact during use.
It helps compare resin grades, fillers, additives, and compound formulations by their impact behavior.
The tester is suitable for material development, batch-to-batch consistency checks, product evaluation, and routine quality control testing.
