Hello everybody, I've got an question I hope you can answer.


The NFPA 25 (2014) says in to do a no-flow test for a minimum of 30 minutes for a dieselengine pump. This is basically a test where the engine will not have a load on it (the engine is idle). My question is, if the enginepump is run with load on it, would a test of 15-20 minutes suffice?


A colleague on engines says that running an engine idle is bad and this would give better results, because only doing a flow test once a year might not be enough if you need the engine to work. I hope you can answer my question. English isn't my main language, I hope you understand the question!
