Re: [MW:32140] interruption limitations to stop welding

i am looking ASME VIII div1 , requirement same above as per project specification below details , I am looking for <19mm 
P1 through P5B materials with wall thickness  19 mm (0.75 in.) shall only be
interrupted provided a minimum of 10 mm (0.375 in.) of weld metal has been deposited or 25 percent of the weld
groove has been filled, whichever is greater. If welding is interrupted, the weld shall be covered with adequate
insulation to ensure slow cooling. The partially completed weld shall be 100 percent MT-inspected prior to
resuming welding.
