Preview
Summary
This document specifies a test method for the determination of brittle crack arrest 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. This document can be applied to flat rolled steel plates but not to flattened steel pipes because
the flattening can cause changes in arrest toughness.
