Izod test

Izod test

[′ī‚zäd ‚test]
(metallurgy)
An impact test in which a falling pendulum strikes a fixed, usually notched specimen with 120 foot-pounds (163 joules) of energy at a velocity of 11.5 feet (3.5 meters) per second; the height of the pendulum swing after striking is a measure of the energy absorbed and thus indicates impact strength.

The most popular test in North America is the notched Izod test while the counterpart that seems to be currently favored in Europe is the Charpy test.
The position of the brittle/tough transition in terms of rubber content determined by the standard notched Izod test is basically the same as that determined by the EWF procedure.
At higher concentrations and temperatures above the glass transition temperature (-28 degC), a no break point in the Notched Izod test can be achieved.
The previously discussed tests are static mechanical properties tests, whereas the Izod test is dynamic.
There is also a specimen support--a vise for the Izod test and an anvil for the Charpy test.
The notched impact strength obtained by the Izod test as a function of EPDM-g-MA composition for PTT/EPDM-g-MA blends is shown in Fig.

The polyethylenes were not broken in the Izod test, and toughnesses were apparently very high; see Table 2.
