3.9.1
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 piping and boiler house equipment, but
and the system proved tight under gauge pressures of 1-1/2 times the
specified working pressure. The boilers shall be tested and the piping
connections inspected by a 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. After flushing and operationally testing, underground
portions of oil containing piping systems shall be leak tested. The test
shall be the [standpipe method] [buoyancy device] type and shall conform to
the requirements in NFPA 329. The test method shall not involve
pressurization of the system in any way which could increase the rate of
product escape through an established leak.

Efficiency and Operating Tests
Upon completion of installation, the boiler plant shall be subjected to
The Contractor shall adjust equipment and controls before the scheduled
operating test. A testing schedule shall be submitted to the Contracting
Officer at least 15 days before the scheduled test. Each operating test
shall be conducted as directed by Contracting Officer.
a. An efficiency and capacity test shall be run on one boiler of each
size installed, conducted in accordance with ASME PTC 4 abbreviated
efficiency test utilizing the heat loss method, except for use of
measuring or metering devices properly calibrated before the test, for
the purpose of metering the water used and weighing the amount of fuel
burned. Water meter used in the test shall be suitable for hot water.
Instruments, test equipment, and test personnel required to properly
conduct tests shall be provided by the Contractor. The necessary fuel,
water, and electricity will be furnished by the Government.
b. The performance tests shall, in each case, cover the periods for
the capacities tabulated below:
