4.6 Tests.
4.6.1 Hydrostatic. The pump and fittings shall be subjected to a hydrostatic
test pressure of a minimum of 30 psig for a period of 15 minutes. Any leakage,
cracking, or permanent deformation of the assembly shall constitute failure of
the test.
4.6.2 Drop test. The pumping unit shall be dropped one time from a height of
not less than 48 inches onto a concrete floor. Nonconformance to 3.11 shall
constitute failure of this test.
4.6.3 Performance.
4.6.3.1 Test conditions. Unless otherwise specified in a test, test shall be
performed in accordance with the applicable provisions of the test code for
centrifugal pumps of the standards of the Hydraulic Institute. All performance
data shall be corrected to standard sea level conditions of a barometric
pressure of 29.92 inches of mercury and liquid fuel at 60
having a specific
gravity of 0.85. Water at a temperature of between 60
and 80
may be used
as the test fluid.
4.6.3.2 Pumping. The pumping unit shall be operated as specified herein to
determine pump brake horsepower required, pump efficiency, and the net positive
suction head required, based on the data obtained. The resultant data shall be
used to plot the corrected performance characteristics.
4.6.3.3 Priming test. The unit shall be tested on the equivalent to a
10-foot static suction lift and shall fully prime within 2 minutes or less.
Failure to prime in 2 minutes shall constitute failure of test.
4.6.3.4 Operational test and functional test. The pumping unit shall be
operated for 1 hour continuously (as specified in 3.9) at the rated conditions
specified in 3.10 The pumping unit shall be operated as required during this
period to verify the functional operation of the controls, and the pump shall be
examined during the operation for leakage through the pump casing or the shaft
seals and for malfunction of any component. Any leakage attributable to defects
in design, workmanship, materials, or to the malfunction of any component, or
inability of the pump to deliver the minimum capacities specified herein shall
constitute failure of this test.
