It involves striking a specimen with a cold-pressed notch to measure the shear area percentage; a minimum of 85% shear average is typically required for a passing result.

Requirements for the anvil support, the dropping weight (ram), and striking characteristics.

The primary objective of the DWTT is to determine the percent shear area of a fracture surface at various temperatures. The transition from a ductile (shear) fracture to a brittle (cleavage) fracture is highly temperature-dependent. By testing pipe specimens at various temperatures, engineers can establish a "fracture transition curve." This curve helps operators ensure the pipeline operates at temperatures well above its ductile-brittle transition temperature. Key Guidelines Outlined in the Document It involves striking a specimen with a cold-pressed

While Charpy V-Notch (CVN) testing is common, it may not adequately predict the behavior of high-strength line pipe steels in large-diameter applications. The Drop-Weight Tear Test was developed to better simulate the propagation of a brittle fracture in a pipe.

Personnel handling the tests are trained in metallographic evaluation and fracture surface reading.
