During the 30-minute soak test voltage the test voltage do not lower than. If the pressure in the system to reduce the increasing pressure, and if the pressure exceeds 6%, reducing the voltage down.
Soak for 30 minutes during the test, pressure test ban under pressure. If the pressure in the system is reduced. To increase the pressure and if the pressure exceeds 6% lower pressure drop.
During the test, soak 30 minutes no lower pressure test pressure. If the pressure in the close system. To increase the pressure and if excess pressure 6%, reduce the pressure down.
