It is designed for conducting Izod and Charpy test. The Test method confirms to IS: 1598-1997, 1757-1973, 1499-1977, 3766-1977 as well as BS: 131-Part 1,2,3 & 4 - 1972.
The pendulum is mounted on antifriction bearings. It has two starting positions, the upper one for Charpy and the lower one for Izod testing. One 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 and the height of rise after rupture of the test specimen and is read from the position of maximum pointer on the dial scale.
