mercury-air, mercury-water, a Meriam fluid manometer, or a pressure
transducer. Vacuums shall be measured with either a mercury-air manometer,
a mercury-water manometer, or a pressure transducer. Fluctuations shall be
dampened sufficiently to permit column gauges or a differential pressure
transducer to be read to either the closest one one-hundredth (0.01) of 30
cm 1 ft of water or Meriam fluid or one-tenth (0.1) of 3 cm 1 in. of
mercury. Manometers shall be used as indicated by ISA RP2.1. When
pressure transducers are used, their accuracy shall be checked with a
manometer.
2.10.3.2
Pump Capacity
Capacity shall be determined by a calibrated venturi flowmeter or a
long-radius ASME flow nozzle. Orifice plates shall not be used. Venturi
or nozzle taps shall be connected to column gauges equipped with dampening
devices that will permit the differential head to be determined to either
the closest one-hundredth (0.01) of 30 cm 1 ft or water or one-tenth (0.1)
of 3 cm 1 in. of mercury. Magnetic flowmeters and flowmeters utilizing
ultrasonic flow measurements will be acceptable if the calibration of the
flowmeter has been completed within the last 6 months.
2.10.3.3
Rotational Speed of Pump
Rotational speed of the pump shall be measured in accordance with
measurement of speed in HI 2.6, except that revolution counters shall not
be used. The device used shall permit the speed to be determined to 1 rpm.
2.10.3.4
Power Input
Power input to the pump shall be measured in accordance with power
measurements in HI 2.6. A method to permit kW bhp to be determined to the
closest 0.5 bkW 0.5 bhp shall be used.
2.10.4
Witness Test
Factory test shall be performed in the presence of the Contracting Officer.
When the Contractor is satisfied that the pump performs in accordance with
the specified requirements, the Contracting Officer shall be notified, two
weeks in advance, that the witness tests are ready to be run and furnish
two copies of curves required in paragraph TEST RESULTS above. Should the
test reveal that the pump does not perform in accordance with the
specifications, the Contractor shall make necessary changes before again
notifying the Contracting officer that witness tests are ready to be run.
Copies of all data taken during the testing and plotted preliminary curves
shall be given to the Contracting Officer at the conclusion of the test.
2.10.5
Factory Test Report
Each factory test report shall include, as a minimum, the following:
a. Statement of the purpose of test, name of project, contract number,
and design conditions. Instances where guaranteed values differ from
specified values should be given.
b.
Resume of preliminary studies, if such studies were made.
c. Description of pump and motor, including serial numbers, if
available.
