Charpy Impact Test

Exova routinely conducts charpy impact tests, which provide a measure of a metal's toughness.

Charpy impact test specimens are cut from metal samples, and a V-notch is placed in the center. Charpy impact testing can be performed at ambient and low temperatures (down to -325°F). Three charpy test specimens are assessed, often in accordance with the ASTM standards.

Low temperature charpy testing involves placing the specimens into a chamber bath of propylene glycol, adding dry ice, and leaving specimens while a calibrated thermocouple records the temperature required for the test. Charpy test specimens are then removed from the chamber, and immediately tested for joules/lbs force by a swinging arm pendulum (which records the value to propagate the cut V-notch).

Size of specimen required for the charpy test is based on thickness of the metal.
