ISO 148-1
Charpy Impact Testing
Charpy impact testing measures the energy absorbed by a standardised notched specimen when struck by a swinging pendulum. It characterises a material’s toughness and brittle-to-ductile transition temperature. ISO 148-1 is mandatory for structural steels, pressure vessels, and pipelines operating at low temperatures or in impact-prone environments.
What it measures
- Absorbed impact energy (KV2, KU2) in joules
- Lateral expansion
- Fracture appearance (percentage shear area)
- Ductile-to-brittle transition temperature (DBTT)
