Fire pumps are commissioned through a process of approvals regarding the installation and actual flow testing of the unit. The requirements for the initial acceptance of the pump assembly are found in NFPA 20; the requirements for ongoing maintenance, testing and inspection of the assembly are found in NFPA 25, Inspection, Testing and Maintenance of Water-based Fire Protection Systems.
Acceptance and commissioningCommissioning is misunderstood. It is often thought to be the testing of the unit. However, there is more to it than that. Training of the operators of the pump, manuals for care, operation and maintenance, and all required test forms have to be produced before a pump installation is considered to be commissioned. of a fire pump installation will require hydrostatic testing and flushing of piping associated with the fire pump installation. There may also be the need to hydrostatically test the underground that the fire pump will connect to, so that there is assurance that the underground can withstand the higher pressure of the pump.
The pump is tested to ensure that it performs as it did in the factory; the controller is also tested for specific items, such as its ability to start, and sometimes, stop the pump; and also to be sure that any required monitoring of the controller or engine functions operates as it is designed.
