ASTM E436 testing covers the drop-weight tear test (DWTT) on ferritic steels with thicknesses between 3.18 and 19.1 mm (0.125 and 0.750 in.). Results may be used to determine the appearance of propagating fractures in plain carbon or low-alloy pipe steels (yield strength less than 825 MPa). IS : 10623 - 1983 1. SCOPE 1.1 This standard prescribes a method for drop-weight tear test ( DWTT ) on ferritic steels and line pipe 500 mm OD and larger, with thickness between 3.2 mm to 40.0 mm in order to evaluate the nil-ductility transi- tion ( NDT ) temperature. 1.2 This test method is also suitable to determine the appearance of
As the test standard requires only one drop can tear the specimen, there is big residual energy after impact. Sometimes, the residual energy may reach several thousand or even more than ten thousand joules. Under low temperature impact test, the residual energy may be much higher. In this case a damping device is necessary and it will affect . Drop arm test is negative if the patient is able to control the lowering of the arm slowly and without pain.
