the correct assembly in the field.
2.8
NAMEPLATE
The pumping unit shall be identified by means of a separate nameplate
permanently affixed in a conspicuous location. The plate shall bear the
manufacturer's name, model designation, serial number if applicable, and
other pertinent information such as horsepower, speed, capacity, type, and
direction of rotation. The plate shall be made of corrosion-resistant
metal with raised or depressed lettering and a contrasting background.
2.9
INSTRUCTION PLATES
The pumping unit shall be equipped with suitably located instruction
plates, including any warnings and cautions, describing any special and
important procedures to be followed in starting, operating, and servicing
the equipment. Plates shall be made of corrosion-resistant metal with
raised or depressed lettering and a contrasting background.

FACTORY TEST
**************************************************************************
NOTE: The designer should specify performance
testing of the assembled pump in the factory to
check that the requirements of the specification
have been met. Cavitation testing is recommended
but may not always be required. The designer should
include cavitation testing whenever the cavitation
characteristics of the proposed pump have not been
determined (by test) by any one of the prospective
suppliers. Testing should be conducted on a
full-scale (prototype ) pump. It should also
establish the structural and operating integrity of
the complete pumping unit. The prototype pump would
be the first pump built.
**************************************************************************
2.10.1
Performance Test
The pump shall be tested at the manufacturer's shop to demonstrate that the
proposed pump operates without instability and complies with specified
performance. Instability is defined when any point in usable range of the
head-capacity curve cannot be repeated within 3 percent. When this occurs,
the test shall be rerun. Compliance with specifications will be determined
from curves required by the paragraph TEST RESULTS. Test procedures,
except as herein specified, shall be in accordance with applicable
provisions of HI 2.6. The temperature of the water used for testing shall
be approximately the same for all tests run and shall be recorded during
test runs.
2.10.1.1
Performance of the Pump
Performance of the pump shall be determined by a series of test points
sufficient in number to develop a constant speed curve over the range of
total heads corresponding to the requirements of the paragraph CAPACITIES.
The test range shall include additional testing at total heads of0.6 m 2 ft
higher than that specified. The lowest total head for testing shall be, as
a minimum, the total head determined from the referenced paragraph. If the
test setup permits testing at lower total heads, the range of total heads
