(E-5~E-8)Pa.m3/s
According to the outlet pressure, the leakage hole is divided into vacuum (negative pressure) leakage hole and positive pressure leakage hole, which is mainly determined by the use conditions. When the outlet of the leak is to the atmosphere, the standard leak is called a positive pressure leak. For example, the leak with the suction gun method belongs to this category.
