Impact test is the simplest crack resistance testing method. It consists of striking a notched specimen, supported without attachment at each end, with a Charpy pendulum hammer, and measuring the rupture energy. The specimen is positioned so that the hammer strikes opposite the notch. The test result is the energy used to rupture the specimen.
We use Zwick/Roell Type HIT450P Charpy hammer for impact testing.
Impact tests are performed in conformity with the following standards:
PN-EN ISO 9016:2022-09 - Destructive tests on welds in metallic materials — Impact tests — Test specimen location, notch orientation and examination
PN-EN ISO 148-1:2017-02 - Metallic materials — Charpy pendulum impact test — Part 1: Test method
