WARNING
Do not air test the tank. Over pressurization could cause the tank to burst, resulting in
death or serious injury to personnel.
GENERAL
Hydrostatic testing should be performed annually. For tank containers measuring 7.0 foot x 4.0-inch flat,
the test pressure is as follows:
1. Initial pressure equals 4.0 PSI (28 kPa). Torque values for bolts are 70.0 ± 5 ft-lbs (95 ± 7 Nm).
2. Static time equals 7.0 PSI (48 kPa) for two hours.
3. Maximum pressure equals 12.0 PSI (83 kPa).
4. Rise time to maximum pressure equals 10 minutes from 7.0 PSI to 12.0 PSI (48 - 83 kPa).
TANK DEPLOYMENT
1. Set the tank on a smooth area for testing and draining.
2. Place the tank in the test area, making certain that all air has been expelled from the tank by flattening
the tank completely with the pressure/air relief valve open.
3. Close the pressure/air relief valve before beginning the test.
SETTING UP EQUIPMENT
1. Bleed the air from the filling line to prevent air from entering the tank.
2. Attach the supply hose securely.
3. Attach the .25-inch ID hose to the petcock on the flow tube.
4. Close the petcock and turn on the water.
