cover the same phases as those for the field tests. Submit this test plan
along with the field test plan. In no case will the Contractor be allowed
to start performance verification testing without written Government
approval of the performance verification test plan.
The test plan shall
consist of detailed step-by-step instructions for complete testing to prove
control system maintains set points, control loops are tuned, and
controllers are programmed for the correct sequence of operation. The test
plan shall also cover test requirements specified in the PART 3 paragraph
entitled "Performance Verification Test."
3.3.5
Contractor's Field Tests
Field tests shall include the following:
3.3.5.1
System Inspection
Observe the HVAC system in its shutdown condition. Check dampers and
valves for proper normal positions. Document each position for the test
report.
3.3.5.2
Calibration Accuracy and Operation of Inputs Test
Verify correct calibration and operation of input instruments. For each
sensor and transmitter, including those for temperature, pressure,
humidity, and air quality, record the reading at the sensor or transmitter
location using calibrated test equipment. On the same table, record the
corresponding reading at the digital controller for the test report.
The test equipment shall have been calibrated within one year of use. Test
equipment calibration shall be traceable to the measurement standards of
the National Institute of Standards and Technology.
3.3.5.3
Actuator Range Adjustment Test
With the digital controller, apply a control signal to each actuator and
verify that the actuator operates properly from its normal position to full
range of stroke position. Record actual spring ranges and normal positions
for all modulating control valves and dampers. Include documentation in
the test report.
3.3.5.4
Digital Controller Startup and Memory Test
Demonstrate that programming is not lost after a power failure, and digital
controllers automatically resume proper control after a power failure.
3.3.5.5
Surge Protection Test
Show that surge protection, meeting the requirements of this specification,
has been installed on incoming power to the digital controllers and on
communications lines.
