hour written notice shall be submitted to the Contracting Officer
indicating the equipment is ready for inspection or testing. Provide
testing equipment, including gages, thermometers, calorimeter, Orsat
apparatus, thermocouple pyrometers, fuel flow meters, water meters, and
other test apparatus and set up and calibrate prior to the test. Draft,
fuel pressure, and steam flow may be measured by permanent gages and meters
installed under the contract. [Gas flow may be measured by utility company
meters.] Provide an analysis of the fuel being used for tests. Control of
noise levels developed by exhaust steam including muffler, globe, and gate
valves shall be conducted in such a manner as not to create a nuisance or
hazard and shall be subject to the approval of the Contracting Officer.
Tests shall include the following, and shall be performed when feasible, in
the sequence listed:
a.
Strength and tightness tests
b.
Standards compliance tests
c.
Combustion tests
d.
e.
Capacity and efficiency tests
f.
Tests of auxiliary equipment
g.
Feedwater equipment test
3.2.2
Strength and Tightness Tests
**************************************************************************
NOTE: These field tests shall not be mandatory for
all size boilers but shall be employed where advis
able due to largeness, type, or complexity of boiler
plant. The designer shall determine, on a case by
case basis, which tests are appropriate.
**************************************************************************
Subject boiler to the following strength and tightness tests:
3.2.2.1
Hydrostatic Test
After installation and connection, subject [the] [each] boiler to an
inspection and hydrostatic test to determine that the boiler and
appurtenances have not been damaged in transit or handling. The
hydrostatic test shall be in accordance with the ASME Code with the test
pressure applied for a period required by the Contracting Officer. This
test shall be in addition to the hydrostatic tests performed at the
factory. [The hydrostatic test at the site shall be certified by an
inspector holding an authorized commission from the National Board of
Boiler and Pressure Vessel Inspectors.]
3.2.2.2
Pneumatic Tests
Pneumatically test air casing and ducts exterior to the furnace at the
maximum working pressure. Use the soap bubble method to verify tightness.
Test gas sides of boilers normally operated under pressure for tightness at
2.5 kPa (gage) 10 inches water gage. For this test, tightly seal the
boiler with a suitable means to blank off openings. Admit air to the
