3.2.8
Following erection, each boiler shall be tested hydrostatically and proved
tight under a gauge pressure of 1-1/2 times the working pressure specified.
Following the installation of all piping and boiler house equipment, but
before the application of any insulation, hydrostatic tests shall be made
and the system shall be proved tight under gauge pressures of 1-1/2 times
the specified working pressure. Boilers shall be tested and the piping
connections inspected by an NBBPVI-commissioned boiler inspector for
determining compliance with all requirements in ASME BPVC SEC VIII D1, and
the Contracting Officer shall be supplied with a certificate of approval
for each boiler. Shop foam shall be applied to all seams to detect leaks.
Boiler shall not lose more than [1.27] [_____] kPa [5] [_____] inches water
gauge in [10] [_____] minutes.
3.2.9
Test for Steam Purity and Water Level Stability
Test for steam purity, in accordance with ASTM D 1066, and water level
stability shall be simultaneous under the operating conditions specified.
3.2.9.1
Steam Tests
Steam tests for boiler over [2.07] [_____] MPa [300] [_____] psig, without
superheaters, not used for power generation or large turbine drive, shall
be made on steam sampled in accordance with ASTM D 1066, using the
conductivity method in ASTM D 2186. The conductivity of the steam
corrected for carbon dioxide and ammonia content shall not exceed 30
microhms at 18 degrees C. Steam for boilers less than [2.07] [_____] MPa
[300] [_____] psig, with or without superheat, used for power generation or
turbine drive for air-conditioning equipment shall be sampled in accordance
with ASTM D 1066 and shall be tested in accordance with the conductivity
method in ASTM D 2186. The conductivity of the steam corrected for carbon
dioxide and ammonia content shall not exceed 4.0 microhms at 18 degrees C
60 degrees F. Steam shall be tested for moisture in accordance with
calorimetric method outlined in Part II of ASME PTC 19.11.
3.2.9.2
Water Level Stability Test
Water level stability test first shall be conducted by use of the manual
bypass around the feedwater regulator. Test then shall be repeated using
the automatic feedwater regulator. Boiler shall maintain specified water
level stability under both conditions.
3.2.10
Performance Tests
Upon completion of installation, the boiler and associated equipment and
instrumentation shall be subjected to such operating tests as may be
required to demonstrate satisfactory functional operation. [Stack sampling
for compliance with applicable emission limits is covered under Section
[_____].] Testing shall be in accordance with the test procedures
indicated below and shall be in accordance with the requirements of ASME
PTC 19.10. All pressure measurements are to be taken in accordance with
ASME PTC 19.2, and all temperature measurements are to be taken in
accordance with ASME PTC 19.3. The Contractor shall furnish all
instruments, equipment, and personnel required for the tests. The
Government will supply water, electric power, and fuel. Two instruction
manuals shall be available at all times during the tests.
