3.      The operator should be away from the danger zone, and the operator should start the test machine according to the regulations and carry out the drop weight test on the test piece.

4.      After each hammering, check the fracture of the test piece and measure the residual deflection of the test piece.

5.      After the test piece is subjected to the specified number of hammering times, no breakage is passed.

6.      For welded joint specimens that have not been broken after the specified number of hammer strokes, the joints shall be slashed at the bottom corners of the weld rails, and hammering shall continue to break them for analysis of fractures.
