Webb17 mars 2005 · Impact tests are designed to measure the resistance to failure of a material to a suddenly applied force such as collision, falling object or instantaneous blow. The test measures the impact energy, or the energy absorbed prior to fracture. The most common methods of measuring impact energy are the: • Charpy Test • Izod Test What is Impact … WebbImpact (effect of rapid deformation), according to ISO 6272–1 is a falling-weight test, large-area indenter using an Erichsen impact tester. This test method covers a procedure for rapidly deforming by impact a coating film and its substrate and guidelines on how to evaluate the effect of such deformation. The test is performed on 1.5 mm panels.
