Standards
l ISO 179 Part 1 (non-instrumented impact test).
Application
Charpy pendulum impact tester is used to conduct resilience tests on rigid plastic materials in order to determine their impact fragility characteristics under standard stress conditions. The test method conforms to ISO 179 - Part 1 (non-instrumented impact test).
The sample, supported near its ends as a horizontal beam, is impacted by a single blow of a striker, with the line of impact midway between the supports, and bent at a high, nominally constant, velocity.
Features
l Impact speeds of 2.9m/s & 3.8m/s as well as multiple impact energies can be generated by one pendulum.
l High mass, traditional pendulum design concentrates energy at the impact point with minimal energy loss due to vibration.
l The electrics contain a high-resolution encoder for accurate measurement of the impact angel.
l Touch screen control for quick and easy input of parameters
l Results are automatically corrected for energy loss due to air and mechanical friction.
