Izod Impact Test
Testing procedure:
An impact testing machine is shown in the diagram
below. Impact testing tests for toughness. A striker / pendulum is released
from a pre-determined height. It strikes and breaks the specimen. A
pointer indicates the height of the follow through after breaking, thus
determining the energy absorbed in breaking the specimen.
Izod method:
The specimen is held vertically, clamped at one end.
The notch is facing the pendulum.
The striking energy is 167 joules
.
