- Scope
- This standard applies to metal Izod impact tests. The Izod impact test is at room temperature (10-35°C), using cantilever beam impact to measure the energy absorbed when the notch of the sample is broken. The fracture of the sample is accomplished by a single impact of the pendulum. When impacting, the sample is clamped vertically, and the bottom of the notch and the top surface of the positioning block are in the same plane. The pendulum hits the front of the gap at a certain height above the gap.
