Our building has a Nibco F-908-W swing check valve installed downstream from the fire pump between the input to the standpipes. Does NFPA give any specification on leak rate for that valve as specified in MSS SP-71?

Our building has a Nibco F-908-W swing check valve installed downstream from the fire pump between the input to the standpipes. Does NFPA give any specification on leak rate for that valve as specified in MSS SP-71? Our commercial inspector says valves are not permitted any leakage.
