As part of acceptance testing for a fire pump we test the installed pump net pressures at various flows (churn, 100%, 150%) and compare that against the factory certified curve for that specific fire pump.
For these tests, what is the pass/fail threshold?
What would fail this test, and how far off could the installed pump be to fail this test?
As I understand it, the installed fire pump cannot differ from the factory certified curve more than the error in the measurement equipment (the allowed error in gauges, typically 1% of the gauge reading). I'm not sure if that's the proper way to go about it, but was curious if there's a better pass/fail mark I should be looking for with these tests.
