inoperative, and the boiler safety valves shall be lifted by steam.
Determine the relieving capacity, popping pressure, blowdown, and reseating
pressure by observation and measurement to be in accordance with the ASME
Boiler and Pressure Vessel Code. The ASME standard symbol will be accepted
only as indicating compliance with the design and material requirements of
the code.
3.2.5
Capacity and Efficiency Tests
Perform the capacity and efficiency tests after satisfactory completion of
all tests previously specified herein and after the boilers have been
operating [continuously] for [one] [5] [_____] days with no nuisance
shutdowns and without the necessity for frequent or difficult adjustments.
Perform these tests on each boiler. Conduct tests using [the] [each of
the] specified fuels. Test procedures shall be in accordance with the heat
loss method of the ASME PTC 4.1 and shall be reported on the ASME Test Form
for Abbreviated Efficiency Test. The duration of the tests shall be
sufficient to record necessary data but in no case shall test duration be
less than [4] [_____] hours [on each fuel].
3.2.6
Auxiliary Equipment and Accessory Tests
Observe and check blowdown valves, stop valves, try cocks, draft fans, fuel
oil heaters, pumps, electric motors, and other accessories and appurtenant
equipment during the operational and capacity tests for leakage,
malfunctions, defects, noncompliance with referenced standards, or
overloading, as applicable.
3.2.7
Feedwater Equipment Tests
Perform the test of the feedwater treatment equipment in two steps.
Conduct one test by the Contractor concurrently with either the combustion
test or the capacity and efficiency test. A second test will be performed
by the Government during the first period of heavy loading after the plant
has been accepted and put in service. Deficiencies revealed during the
Government tests will be corrected under the guarantee provisions of the
contract. Both the first and second series of tests shall determine
compliance with the limits for oxygen content and hardness concentrations
of this specification. Equipment for taking samples and the test kit for
analyzing the samples shall be supplied by the Contractor and shall revert
to the Government when the tests are completed.
3.2.8
Preliminary Operational Test
Operate each boiler and appurtenances prior to final testing and insure
that necessary adjustments have been made. Provide testing equipment
required to perform tests. During this testing period, provide operating
instructions and training to persons tasked with operation of the boiler.
Tests shall be accomplished with both fuel on dual fuel units.

Conduct a preliminary operational test prior to requesting an acceptance
operational test and inspection by a [_____] Division, Naval Facilities
Engineering Command Boiler Inspector. The Contracting Officer, upon
receipt of the notice from the Contractor, shall request the boiler be
