ommended to be initially performed for
corrosion resistant coated sprinklers,
after the installation has been com-
pleted, to verify the integrity of the cor-
rosion resistant coating. Thereafter,
annual inspections per NFPA 25
should suffice; however, instead of in-
specting from the floor level, a random
sampling of close-up visual inspec-
tions should be made, so as to better
determine the exact sprinkler condi-
tion and the long term integrity of the
corrosion resistant coating, as it may
be affected by the corrosive conditions
present.
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any other
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer should be contacted relative to
any questions.
It is recommended that automatic
spr inkler systems be inspected,
tested, and maintained by a qualified
Inspection Service in accordance with
local requirements and/or national
code.

TABLE B
UL AND C-UL LISTING COVERAGE AND FLOW RATE CRITERIA
NOTES
1. Backwall (where sprinkler is located) by sidewall (length of throw).
2. Requirement is based on minimum flow in GPM from each sprinkler. The indicted residual pressures are based on the nominal
K-factor.
3. The centerline of the sprinkler waterway is located 7/16 inch (11,1 mm) below the deflector (Ref. Figures 1 and 2).
4. Minimum spacing is for lateral distance between sprinklers located along a single wall. Otherwise adjacent sprinklers (i.e., sidewall
sprinklers on an adjacent wall, on an opposite wall, or pendent sprinklers) must be located outside of the maximum listed protection
area of the extended coverage sidewall sprinkler being utilized.
