Scope

This document specifies the test principles, test equipment, samples, test methods, test procedures, calculation of fracture toughness, and test reports for determining the fracture toughness Kca of metal materials.
This document is applicable to ferritic rolled flat steel plates with a tensile strength of no more than 1,150 MPa, a fracture toughness temperature range of -196°C to 100°C, and a thickness of no more than 200 mm that exhibit brittle-ductile transition characteristics. However, it is not applicable to steel plates formed by flattening pipe materials, as flattening may cause changes in fracture toughness.
