Efficiency and Operating Tests
Upon completion, and before acceptance of the work, the heat recovery plant
shall be subjected to such operating tests as may be required to
demonstrate satisfactory functional operation. Each operating test shall
be conducted at such times as the Contracting Officer may direct. Water
meter used in the test shall be suitable for hot water. Instruments, test
equipment, and test personnel required to properly conduct all tests shall
be provided by the Contractor and the necessary fuel, water, and
electricity will be furnished by the [Government] [_____]. The boiler
operating tests shall, as a minimum, be conducted continuously at the
following capacities for the following time:

Firebox boiler shall not be operated above 100 percent of capacity.
b. The general performance tests on the heating plant shall be conducted
by an experienced test engineer and will be observed by the Contracting
Officer. A test report including logs, heat balance calculations, tabulated
results, and conclusions shall be delivered to the Contracting Officer as
stated in the paragraph "PERFORMANCE TEST REPORTS." [An analysis of the
fuel being burned on the test shall be submitted to the Contracting
Officer.]
c. Test of capacity of water treatment equipment and quality of the
effluent shall meet the requirements specified. Tests for ion-exchange
units shall cover at least two complete regenerations and capacity runs.
Tests for hot process or other precipitation type softeners shall be
conducted continuously for a period of at least 48 hours, with samples
taken at 2-hour intervals.
d. Tests for steam quality in accordance with ASTM D 1066 shall be
conducted under the operating conditions specified.
e. Quality of steam used for air conditioning equipment shall be tested in
accordance with the conductivity method in ASTM D 2186 with the
SECTION 15845A
