[MW:13697] Re: Drop Weight Test.

The drop weight test (DWT) is a testing procedure where the behaviour
of material on brittle, extending crack is investigated.
During the test only test condition modified is temperature.
Now the term Nil ductility temperature (NDT) is that temperature where
a test piece break through while at 5K higher testing temperature, two
furhter test peices of the same material do not break any more is
called NDT.
The testing creteria is same as told by Mr. Gosawmi.
