PENDULUM IMPACT TESTER (CHARPY, IZOD IMPACT TESTING MACHINE)





Description:

 

PENDULUM IMPACT TESTER (CHARPY, IZOD IMPACT TESTING MACHINE): 

AS PER IS: 1598-1997, 1757-1973, 1499-1977, 3766-1977 as well as BS: 131-Part 1, 2, 3 & 4- 1972 and ASTM E 32-47T.

 

Introduction:

Our Pendulum Impact Tester is designed for conducting Izod and Charpy test. The Test methods 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 and the height of rise after rupture of the test specimen and is read from the position of maximum pointer on the dial scale.

 

General Description and Features:

The machine will have following features:             

  • Capacity       : 300 Joules                             
  • Resolution    
    • 2 Joules for Charpy Test. 
    • 1 Joules for Izod Test                  
  • Accuracy   : Within 0.5 %                            
  • Release of Pendulum by Hand operation.              
  • Safety guards for Protection.                       
  • Assembly to hold standard Izod and Charpy Specimens.
  • Braking Arrangement provided to arrest the swing of pendulum after specimen rupture.                    
  • Standard size specimens of Izod Impact and Charpy 2 nos for each.
