The Problems with Single-Point Data.

The author compares the most often used tests to measure impact performance in plastics which are Izod and Charpy. Topics he covered include the association between strength and stiffness and load-bearing performance, the reason impact resistance is almost always at odds with load-bearing properties and the impact of temperature on plastics during material formulations. The drivers for the plastics industry to consider ductile-to-brittle transition temperature are also mentioned.
