Instrumented Izod Pendulum Impact
A Dynatup POE 2000 apparatus is used to impact a specimen. Specimens are bars with dimensions specified in ASTM and notched accordingly. Sample is clamped vertically, with notch on impact side. Machine is connected to a computer to give load deflection curve. At set velocity and energy, pendulum is released to impact specimen. Test is complete when pendulum completes one swing. Five replicates are performed.
Izod impact strength and corresponding load-deflection traces are provided. This data appears in

This test is used as a means of quality control or materials specification. It can, in some cases, be used on a finished product to determine if the part will fracture under the set conditions. Data gathered from this test are valuable for comparative purposes, to aid the engineer in choosing an appropriate material for a specific application.
