●● The standard shall apply to combined service mains intended to carry
water for fire service and other uses
Answer:
●● This standard shall NOT apply to the following situations
Answer: -Mains under the control of a water utility
-Mains providing fire protection and/or domestic water that are privately
owned but are operated as a water utility
●● The standard shall NOT apply to underground fire mains serving
sprinkler systems designed and installed in accordance with NFPA 13R
that are less than 4 in in nomimal diameter
Answer:
●● The standard shall not apply to underground mains serving sprinkler
systems designed and installed in accordance with NFPA 13D
Answer:
,●● The Purpose of this standard shall be to provide a reasonable degree
of protection for life and property from fire through installation
requirements for private service main systems based on sound
engineering principles, test data, and field experience.
Answer:
●● The provisions of this standard reflect a consensus for what is
necessary to provide an acceptable degree of protection from the hazards
addressed in this standard at the time the standard was issued.
Answer:
●● Residual Pressure
Answer: 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
Answer: The pressure that exists at a given point under normal
distribution system conditions measured at the residual hydrant with no
hydrants flowing.
●● Check Valve
Answer: A valve that allows flow in one direction but prevents flow in
the opposite direction.
, ●● Indicating Valve
Answer: A valve that has components that show if the valve is open or
closed. Examples are outside screw and yoke (OS&Y) gate valves and
underground gate valves with indicator posts.
●● Dry-Barrel Hydrant
Answer: Fire hydrant that has its operating valve located at the base or
foot of the hydrant rather than in the barrel of the hydrant. When
operating properly, there is no water in the barrel of the hydrant when it
is not in use. These hydrants are used in areas where freezing may occur.
●● Flow Hydrant
Answer: The hydrant that is used for the flow and flow measurement of
water during a flow test.
●● Private Fire Hydrant
Answer: A valved connection on a water supply system having one or
more outlets that is used to supply hose and fire department pumpers
with water on private property.
●● Public Hydrant
Answer: A valved connection on a water supply system having one or
more outlets that is used to supply hose and fire department pumpers
with water.
