factory.
Field testing shall be conducted to ensure proper
alignment and installation, start-up and shutdown
procedures, checking out controls, and establishing
baseline measurements. Two field test methods are
available, dry or wet testing, depending on
availability of water. Wet testing is preferred,
but dry testing may be all that is possible when the
pumps are prepared for initial start-up.
If a wet test cannot be conducted at the time of
initial start-up because of a lack of water, it
should be conducted at a later time, if possible,
and does not unduly extend the contract period.
**************************************************************************
Field testing shall be conducted by an experienced field test engineer and
will be witnessed by the Contracting Officer. Before initially energizing
the pump/motors, the Contractor shall have successfully tested all pumping
plant control, monitoring, and protective circuits. This thorough
electrical checkout procedure shall have followed a detailed step-by-step
approved test plan. The motor and other pumping unit elements undergoing
tests should also be checked at this time.
3.3.1
Dry Test
Each pumping unit shall be tested in the dry in accordance with the pump
manufacturer's instructions to determine whether it has been properly
installed. Such tests shall be made when, and as, directed by the
Contracting Officer. The pump shall be operated at full rated speed.
Should tests reveal a design or installation deficiency or a manufacturing
error in pumping unit components, the problem shall be promptly corrected
by and at the expense of the Contractor.
3.3.2
Wet Test
Each unit shall be given an operating test under load for a period of at
least [_____] hr or as directed by the Contracting Officer. The tests
shall be conducted by the Contractor and will be witnessed by the
Government. During the tests, the operation of the pumping units shall be
observed and measurement of [noise (in accordance with HI 9.1-9.5),]
motor-bearing temperatures, voltage, and current shall be recorded for each
pump. Measured parameters shall be within the pump manufacturers published
limits. Vibration measurements shall be made at the top of the discharge
tube [and flange of the discharge elbow] for each pump. Vibration limits
shall not exceed those recommended by HI 9.6.4. Without additional cost to
the Government, the Contractor shall make all changes and correct any
errors for which the Contractor is responsible.
3.3.3
Field Test Report
A test report of the field testing and a manual of Operating and
Maintenance Instructions for the completed system shall be prepared and
submitted in accordance with paragraph SUBMITTALS.
