  "term": "Charpy test",
  "field": "Oil and gas",
  "definition": "A standardized high strain-rate test that measures the energy a material absorbs during fracture, which indicates its notch toughness. A swinging pendulum strikes a notched specimen of a specified size, and the energy absorbed by the sample is calculated from the height the pendulum reaches after breaking it. This test determines a material's tendency to exhibit brittle versus ductile behavior, particularly for steel used in pipelines and pressure vessels at low temperatures.",
