NFPA 24 (TFM10) - FIRE SPRINKLER
UNDERGROUND TEST REVIEW. EXAM
2025 QUESTIONS AND ANSWERS
Residual Pressure - ANS The pressure that exists in the distribution system, measured at the
residual hydrant at the time the flow readings are taken at the flow hydrants.
Static Pressure - ANS The pressure that exists at a given point under normal distribution
system conditions measured at the residual hydrant with no hydrants flowing.
Flow Test - ANS A test performed by the flow and measurement of water from one hydrant
and the static and residual pressures from an adjacent hydrant for the purpose of determining
the available water supply at that location.
Flushing Test - ANS A test of a piping system using high velocity flows to remove debris from
the piping system prior to it being placed in service.
Hydrostatic Test - ANS A test of a closed piping system and its attached appurtenances
consisting of subjecting the piping to an increased internal pressure for a specified duration to
verify system integrity and system leakage rates.
Check Valve - ANS A valve that allows flow in one direction only.
Indicating Valve - ANS A valve that has components that provide the valve operating
condition, open or closed.
