leakage will be found
3) Pressurize for about 24 hours at 3.0MPa(30 kg/cm g). A small
leakage will be found.

If the pressure does not drop, then pass.
If the pressure drops, then please check the leaking point.
When pressurizing for 24 hours, a variation of 1 in the ambient temperature will cause a variation of 0.01MPa(0.1kg/cm g)
in pressure.
