What Does DWTT Stand For?

DWTT stands for Drop Weight Tear Test

DWTT, or Drop Weight Tear Test, is a standardized method used to evaluate the impact toughness and fracture behavior of materials, particularly in pressurized service applications. This test involves the free fall of a weight onto a notched specimen, simulating conditions that materials may encounter in service. The results provide essential information regarding the material's ability to absorb energy and resist crack propagation under sudden impact, which is crucial for ensuring structural integrity and safety in engineering applications.
