The various methods allows for the determination of the necessary energy to break a specimen – having a known cross-section - then calculating its resilience value at a given conditions. The potential energy of the hammer is known and it varies depending on the hammer’s shape, weight and release angle. The absorbed energy to break the specimen can be determined after measuring the ascent angle of the hammer after the impact. The test methods to perform with this structure are Charpy, Izod and Tensile Impact. Differences among these test methods are related to the way the specimen is mounted and how it is impacted.


Charpy method:
The specimen, rectangular shaped, is positioned horizontally and is broken
with one oscillation of the hammer only; the impact line is centred between
the two specimen supports.
Izod method:
Specimen, rectangular shaped, is blocked at one end in vertical position and
it is broken with one oscillation of the hammer only; the impact line is at a
fixed distance from the blocking point of the specimen.
Tensile impact method:
Specimen is inserted in two blocking brackets and it is broken with only one
oscillation of the hammer which stresses the specimen, dumb-bell shaped,
along its longitudinal axis
