3.3.1.2
Instrumentation Test
The Contractor may use instrumentation provided in the contract and
instrumentation provided by the Contractor to conduct the test. The
testing procedure and instrumentation shall be submitted to the Contracting
Officer for approval prior to conducting tests. The format of ASME PTC 9
is required. It is intended that a full field test be performed. However,
in lieu of precise instrumentation, the Contractor may use certified
cooling water pump curves[ and [cooling tower] [closed circuit cooler] fan
curves]. Shutdown signals shall be caused by throttling selected fluids.
Test data, such as air intake temperature and humidity, shall be
mathematically corrected to performance test requirement levels.
3.3.1.3
Sound Level Tests
Sound level tests shall be conducted concurrently. Broad Band "A" scale
readings and Octave Band readings shall be taken and recorded at the same
positions as on the factory testing. Maximum permissible level shall be 84
decibels one horizontal meter from the compressor and 1.5 meters above the
floor, with unit in operation and all other significant equipment not
required for test within the same building bay shutdown at the same
location previously described. A background noise correction to 60
decibels is permissible.
3.3.1.4
Operational Deficiencies
Any operational deficiencies noted in the tests shall be promptly corrected
and affected portions of the test rerun.
3.3.1.5
Field Test Tolerances
A tolerance of plus or minus 2 percent on flow, plus or minus 4 percent on
power, or plus or minus 5 percent on any other variable for each item of
equipment or fluid with all others conforming is permissible on field test
results when compared to factory test data and to guarantee performance
data except that compressor air flow, discharge pressure, and motor power
shall be met.
3.3.2
Approval of Testing Procedure
Proposed testing procedure shall be approved by the Contracting Officer and
the individual in charge of testing prior to conducting tests.
3.4
TRAINING OF GOVERNMENT PERSONNEL
During start-up and field testing, train Government station personnel in
the operation and maintenance of compressor, [cooling tower,] [closed
circuit cooler,] associated equipment, and all control and safety devices.
Training shall not commence until equipment is operational and station
personnel are in attendance. At least one day of classroom training and
one day of field training shall be furnished for each designated Government
personnel. When factory training is required by the compressor
manufacturer for proper maintenance and overhaul of the compressor, such
training will be furnished by the compressor manufacturer at no additional
cost to the Government. The Government will bear the cost of travel and
living expenses for Government personnel as necessary for the factory
training.
