Battelle drop weight tear test

The Battelle drop weight tear test allows investigating and characterising brittle and ductile fracture resistance in full thicknes samples. The instrumented tester measures the amount of force required to break a specimen at a certain test temperature, and this enables calculating separate values for initiation energy and propagation energy. BDWTT tests are typically used to characterise the type of fracture in pipeline steels and are standardized in API 5L3 and EN 10274.
