Tinius Olsen manufactures several high capacity pendulum impact testers, most of which can be easily changed from a Charpy to an Izod configuration or even to a tensile impact configuration. These testers come in several capacities and are designed primarily for determining the impact resistance of metals. They are designed to fully comply with the specifications outlined in ASTM E23, BS EN ISO 148-3, BS EN ISO 148-2 and ISO 442.

In addition to the high energy impact models, Tinius Olsen manufactures a range of low energy pendulum impact testers that can also be easily changed from a Charpy to an Izod configuration. These testers come in a couple of capacities and are designed primarily for either plastics or metals impact testing.
