Each new fire pump shall be given an acceptance test for one hour and shall deliver its rated capacity at the required speed and net pressure. Pumps rated at less than 1,500 gpm shall deliver 150 percent of the rated capacity at 65 percent of its rated pressure. The test shall not cause the bearings in the pump or on its motor, engine or turbine to become excessively heated. On electric driven fire pumps, there shall be no increase in the temperature of the electric wiring, electric windings of the motor and electric current carrying devices on the control panel other than as noted on the ratings of the various equipment.
Automatic operation of the fire pump shall be verified by a pressure drop in the system. The test shall include manual starting and stopping of the pump.
All electric wiring to the fire pump motor including the controller, emergency power supply, and pressure maintenance pump shall be completed prior to the acceptance test. The pressure at the intake side of the pump shall not be less than five pounds per square inch under any flow rate.
An acceptance test shall be performed on any pump in which the impeller is replaced or repaired.
All such tests shall be performed by an independent contractor licensed under the Illinois Fire Sprinkler Contractor Licensing Act in the presence of the Fire Commissioner.
