Metallic materials. Steel. Method of test for the determination of brittle crack arrest toughness, <i>K</i>_ca Ingestion-build-81500 This standard supersedes BS EN1 Scope This document specifies a test method for the determination of brittle crackarrest toughness. It is applicable to ferritic steel base metals exhibiting ductile to brittle transition behaviour. Applicable materials are rolled steel plates. It is intended for materials with a tensile strength of 950 MPa or less and a test piece thickness of 200 mm or less. The range of arrest temperatures is between 196 C and +100 C.
