Description and Specification for Lab Tenders
Impact Testing Machine.
The Pendulum is mounted on antifriction bearings.
It has two starting positions, the upper one for Charpy and the lower one for Izod testing.
On release, the pendulum swings down to break the specimen and the
energy absorbed in doing so is measured as the difference between the
height of drop before rupture & height of raise after rupture of the
test specimen and is read from the maximum pointer on the dial scale.
Controls of Pendulum:-
The Pendulum supported in the starting position is by a self-resetting latch.
The release mechanism is operated by the lever.
The pendulum release latch is operated only when this lever is operated.
Strikers and Supports:-
There are two strikers & one combined support available for fitting
into the Pendulum & on to the base of the machine for Izod, Charpy
Changing from one striker to another is achieved simply by fixing the new striker into its position
