Charpy
impact test method for metallic materials is specified by
European EN 10045 standard. 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. 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.
 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.
 National
standards corresponding to
EN 10045-2 are DIN
51306 (1983), BS 131 Part 4 (1972) and international ISO 442
(1965).
