3.3.2
Systems in Other Areas
Provide primed surfaces with two coats of paint to match adjacent surfaces,
except provide valves and operating accessories with one coat of FS TT-E-489
red enamel applied to a minimum dry film thickness of 0.025 mm 1.0 mil.
Provide piping with 50 mm 2 inch wide red enamel bands or self-adhering red
plastic tape bands spaced at maximum of 6 meters 20 foot intervals
throughout the piping systems[, except in finished areas, such as offices,
red bands may be deleted].
3.4
CORROSION AND FUNGUS PREVENTION
Protect metallic materials against corrosion. Coat outdoor equipment with
a rust inhibiting treatment and standard finish by the manufacturer. Do
not use aluminum in contact with the earth. Protect dissimilar metals with
approved fittings and treatment. Coat steel conduits installed underground
with an approved asphaltic paint or plastic coating, or wrap with a single
layer of a pressure sensitive plastic tape, half-lapped. Protect
components against corrosion and fungus.
3.5
FIELD QUALITY CONTROL
Perform tests to determine conformance with specified requirements in the
presence of the Contracting Officer.
3.5.1
Tests During Installation
Pneumatically test each piping system at 1034 kPa (gage) 150 psigfor a
2-hour period with no leakage or reduction in gage pressure. Gages shall
be calibrated. Upon completion and before final acceptance of the work,
test each piping system by discharging a minimum of 45.40 kg 100 pounds of
carbon dioxide to demonstrate reliability and proper functioning of
pressure-operated switches and discharge of carbon dioxide gas from each
system discharge nozzle. After discharge, clean wire screens at nozzles,
when provided. When screens or nozzles show evidence of plugging, discharge
and additional 45.40 kg 100 pounds with the nozzles removed. Individually
test remote control stations and other components and accessories to
demonstrate proper functioning. Correct deficiencies prior to formal
functional and operating tests of the system. Furnish carbon dioxide
required for tests.
3.5.2
Final Performance and Acceptance Tests
After the system has been in service for at least 30 calendar days, notify
the [_____] Division, Naval Facilities Engineering Command, Fire Protection
Engineer, in writing that the system is ready for final acceptance tests.
Furnish notification at least 15 calendar days prior to the date of the
final acceptance test. Consider the system ready for testing after
necessary preliminary tests have been made and deficiencies have been
corrected to the satisfaction of the equipment manufacturer's technical
representative and the [_____] Division, Naval Facilities Engineering
Command, Fire Protection Engineer. An experienced technician regularly
employed by the system installer shall be present during the inspection.
3.5.2.1
Acceptance Testing
Furnish proposed test procedures for approval at least 60 calendar days
prior to commencement of acceptance testing. Perform the tests in the
presence of the [Corps of Engineers, Contracting Officer] [[____] Division,
