Pressure Testing
1 3 bar (N2) (44psi or 300kpa)
2 15 bar (N2) (217psi or 1500kpa)
3 32 bar (N2) (464psi or 3200kpa)
pressure should be held for a minimum of 24 hours. Taking into
Triple evacuation method statement
Evacuate the system to 10000 Micron from both service valves. System manifold gauges must not be used to measure vacuum. A Torr or Micron gauge must be use at all times.Break the vacuum with Nitrogen (N2) into "suction" service valve port till 1 Bar(100 Kpa) has registered at the"discharge"service valve port.
3Evacuate to 5000 Micron from "discharge"service valve port.
4Repeat step 2. Then continue to step 5.Evacuate through both service valves to the lowest pressure vacuum pump will achievebelow 500 Microns for 1 hour minimumPressure Rise Test must then be carried out for a minimum of 30 minutes. If the pressurerises on the Torr or Micron gauge repeat steps 2 and 5 till no rise is detected.
