3.2.4
Pipe Sleeves
Pipes passing through construction such as ceilings, floors, or walls shall
be fitted with sleeves. Each sleeve shall extend through and be securely
fastened in its respective structure and shall be cut flush with each
surface. The structure shall be built tightly to the sleeve. The inside
diameter of each sleeve shall be a minimum of 15 mm 0.6 inch larger than
the outside diameter of the passing pipe or pipe covering, and where pipes
pass through combustible materials, 25 mm 1 inch larger than the outside
diameter of the passing pipe or pipe covering.
3.3
ELECTRICAL INSTALLATION
Electrical installation shall comply with NFPA 70, IEEE C2, and Section
16402 INTERIOR DISTRIBUTION SYSTEM. Vibration isolation shall be provided
for all conduit, cable trays, and raceways attached to the engine.
3.4
ONSITE INSPECTION AND TESTS
The tests outlined in the subsequent subparagraphs shall be performed after
complete installation of each engine and its associated equipment and in
accordance with the approved Dynamic Analysis of Engine, Pump, and Governor.
Data taken during runs shall be recorded at 30-min intervals and shall
include all available pressure and temperature data which is monitored by
the instrumentation furnished with the engine.
3.4.1
Contractor Supplied
The Contractor shall provide all equipment and supplies required for the
inspections and tests including fuel and test instruments.
3.4.2
Instruments
Readings of panel gauges, meters, displays, instruments, etc. provided
under the specification shall be verified during all test runs by test
instruments of greater precision and accuracy than the operational
equipment. Instruments used in the tests shall be calibrated by a
recognized standards laboratory within 30 days prior to testing.
3.4.3
Sequence
The tests shall follow the sequence outlined in subsequent paragraphs.
Measurements shall be made and recorded of all parameters necessary to
verify that each engine meets specified parameters. If the results of any
of the test sequences are not satisfactory, adjustments or replacements
shall be made and the test sequence repeated until satisfactory results are
obtained.
3.4.3.1
Piping Test
a. Lube-oil and fuel-oil piping shall be flushed with the same
type of fluid intended to flow through the piping, until the
out-flowing fluid is free of obvious sediment and emulsions.
b. The lube oil, fuel-oil and coolant piping [and piping and
pressure vessels of the air starting system] shall be
hydrostatically pressure tested at 150 percent of the maximum
anticipated working pressure, but in no case less than 1.03 MPa
150 psig for a period of 2 hr to demonstrate the piping has no
