                 Synopsis: 
                        To ensure safety and reliability of rolling stocks, axles are required to be examined 
                 periodically for presence of cracks. This report describes the details of work carried out on 
                 standardization of Ultrasonic Testing Technique for above axle in service by far end, trace-
                 delay,  Near-end  low-angle  scanning  &  High-angel  scanning  using  pulse  echo  reflection 
                 technique.  This  procedure  is  applicable  for  axles  in  service  and  intended  to  be  used  by 
                 ultrasonic personnel trained and certified by RDSO.
