CHARPY IMPACT TESTING LAB
Charpy impact testing (also known as a Charpy V-Notch test) is a valuable method to determine the amount of energy a material absorbs during fracture. The test is performed when a pendulum head is dropped from a specified height and impacts a notched specimen of material. By comparing the difference in the height of the hammer before and after the fracture, one can measure the energy absorbed.
Charpy Impact Test Factors
Notch Toughness
Specimen’s toughness is exhibited while testing through the measure of energy absorbed during impact. Notch dimension and size are also considered during testing.
Temperature-Dependent Ductile-Brittle Transition
Compared by looking at the shear areas of broken Charpy specimens to estimate a percentage of each.
Per Specifications
Tests can be performed at exact temperatures from -320°F to 400°F
- ASTM A370
- ASTM E23
- ISO 148-1
- JIS Z 2242
