CHARPY IMPACT TESTER
Charpy impact tester is used for metallic materials.This specification defines terms, dimension and tolerances of test pieces, type of the notch (U or V), test force, verification of impact testing machines etc. For certain particular metallic materials and applications, Charpy impact test may be the subject of specific standards and particular requirements. The test consists of breaking by one blow from a swinging pendulum, under conditions defined by standard, a test piece notched in the middle and supported at each end. The energy absorbed is determined in joules. This absorbed energy is a measure of the impact strength of the material.
Testing machine:
The testing machine shall be constructed and installed rigidly. Standard test condition shall correspond to nominal machine energy of 300±10J at the use of a test piece of standard dimensions.
