NFPA 24 (TFM10) - Fire Sprinkler
Underground Test Review
"D" in Hydrostatic Testing Allowance Formula - ANS-Nominal diameter of pipe (inches)
"L" in Hydrostatic Testing Allowance Formula - ANS-Testing allowance (make-up water) [gph
(gallon/hour) ]
"P" in Hydrostatic Testing Allowance Formula - ANS-Average check strain for the duration of
hydrostatic take a look at (gauge psi)
"S" in Hydrostatic Testing Allowance Formula - ANS-Length of pipe examined (ft)
two hundred psi or 50 psi above device operating strain @ 2 hour maintain - ANS-What
strain do piping and attached appurtenances want to hydrostatically examined at?
32 in - 40 in (800 mm to 1000 mm) - ANS-Height at which put up indicator valves are to be
set above very last grade.
6 in - ANS-The connection from the hydrant to the main shall no longer be much less than
_____.
6 in (one hundred fifty mm) - ANS-For mains that supply fire hydrants, pipe length shall not
be less than _____.
Authority Having Jurisdiction (AHJ) - ANS-May be a federal, state, neighborhood, or different
regional branch or individual consisting of a fire leader; hearth marshal; chief of a fire
prevention bureau, labor department, or fitness department; constructing professional'
electrical inspector; or others having statutory authority.
AWWA C900 - ANS-Standard for PVC strain pipe and fittings, 4 in through sixty three in
Check Valve - ANS-A valve that permits drift in one course most effective.
Control valve - ANS-A listed _____ _____ will be hooked up in each hydrant connection.
Dry Barrel Hydrant (Frostproof Hydrant) - ANS-A kind of hydrant with the principle
manipulate valve below the frost line between the footpiece and the barrel.
Flow Hydrant - ANS-The hydrant this is used for the waft and drift measurement of water all
through a go with the flow test.
Flow Test - ANS-A take a look at accomplished via the glide and measurement of water from
one hydrant and the static and residual pressures from an adjacent hydrant for the motive of
figuring out the available water supply at that region.
Flushing Test - ANS-A test of a piping gadget using high velocity flows to do away with
debris from the piping machine prior to it being positioned in provider.
Hydrostatic Test - ANS-A take a look at of a closed piping machine and its attached
appurtenances together with subjecting the piping to an extended internal stress for a
specified length to affirm machine integrity and machine leakage charges.
Hydrostatic Testing Allowance Formula - ANS-L = (S * D * sqrt"P") / 148,000
Indicating Valve - ANS-A valve that has additives that provide the valve running
circumstance, open or closed.
Private Fire Hydrant - ANS-A valved connection on a water deliver gadget having one or
extra shops this is used to supply hose and fireplace department pumpers with water on
non-public property.
