Leakage standard notes

1. Every minute bubble numbers is used outside diameter 6mm, wall thickness 1mm tubes vertical submerged underwater 5 ~ 10mm depth conditions to measure, the pipe surface should be smooth.
2. If the seat diameter and listed value differ aboveo 2mm, leaking coefficient can be assumed leakage and seat diameter is directly proportional to the situation through internal extrapolation to obtain.
