#I would like to request your clarification for below standard as we have doubt to compare the pump test result which we recently done.
220.127.116.11.3 (2) Fire pump test results are no less than 95 percent of the
flow rates and pressures at each point for either a or b – at each point means? Does it require to compare all 0% flow and pressure , 100% flow and pressure and, 150 flow and pressure with unadjusted field curve or fire pump nameplate?
Moreover, in our fire pumps there are only rated flow, rated head and rated RPM mentioned, there is no 150% flow and head mentioned. On the other hand, manufacturer took 10 nodes ( pressure, flow, rpm & power) and finally, the supplier referred 100% flow and pressure ( unadjusted data) with name plate data.
NFPA 25 (2017)
18.104.22.168.3 The fire pump test results shall be considered accept‐
able if both of the following conditions are satisfied:
(1) Fire pump can supply the full system demand as provided
by the owner.
(2)* Fire pump test results are no less than 95 percent of the
flow rates and pressures at each point for either a or b:
(a) Original unadjusted field test curve
(b) Fire pump nameplate
We had an audit few weeks back and one of the auditors told us to compare the all the 0% flow & pressure, 100% flow & pressure and 150 flow & pressure with commissioning curve to determine whether the pump is passed.
We have compared our latest test report with 100% flow and pressure of commissioning report.
Do we require to compare the 2019 field test 150% flow & pressure with commissioning 150 % flow & pressure? Kindly advise me
