Impact Tester


Impact Tester Model JIT - 30 is designed for conducting CHARPY, IZOD ans IMPACT TENSION tests. The test methods confirm to IS 1757-1761, IS : 1499-1959 and BS : 131:131 : Part 2 & 3, IS:1598-1960, BS : 131 part I and ASTM E 32-47T.

The impact energy absorbed by the specimen during rupture 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 on the dial scale.

Salient Features :

  • Release of pendulum by 'two hand operation'.
  • Safety guards for protection.
  • Breaking arrangement is provided for stopping the pendulum.

Coupled with experience and expertise gained by manufacturing testing machines since 1966, the new "Justy" Impact Tester provides easy operations, reliability and consistency.

Note :Customised special purpose Impact Testers as per your requirement and usage are also manufactured as per I.S, B.S & A.S.T.M and D.I.N. Standards.
