1.1 This test method covers the determination of fracture propagation toughness in terms of the steady-state crack-tip-opening angle (CTOA) using the drop-weight tear test (DWTT) specimen. The method is applicable to pipe steels that exhibit predominantly ductile fracture with at least 85% shear area measured according to Test Method E436 – Standard Test Method for Drop-Weight Tear Tests of Ferritic Steels. This test method applies to steel pipes with wall thicknesses between 6 mm and 20 mm.
