Method for determining the Izod impact strength of plastics. The test method allows to determine the behaviour of brittleness or toughness. Suitable for the following material groups:
– stiff thermoplastic injection moulding and extrusion moulding compounds
– stiff thermoset plastic materials
– filled and reinforced composites
– fibre-reinforced thermoset and thermoplastic composites with unidirectional or non-unidirectional reinforcement.
The method is adapted to the use of test specimens made from moulding compounds in the selected dimensions, worked out from the central part of the standardised multi-purpose test specimen (see ISO 3167) or taken from mouldings and semi-finished products, such as injection mouldings, laminates, extruded or cast sheets.
