herein before][submit the field test plans at least 90 calendar days prior
to planned date of the field test]. Field test plans developed by the
installing Contractor, or the equipment sales agency furnishing the CRACU,
will not be acceptable.
The Contracting Officer will review and approve the field test plan for
each of the listed CRACU's prior to commencement of field testing of the
equipment. The approved field test plans shall be followed for the field
tests of the CRACU and test reporting.
3.3.1.1
Coordinated Testing
Indicate in each field test plan when work required by this section
requires coordination with test work required by other specification
sections. Furnish test procedures for the simultaneous or integrated
testing of: CRACU controls which interlock and interface with controls
factory prewired[; and external controls for the CRACU provided under
[Section 15901N SPACE TEMPERATURE COTROL SYSTEMS][Section 15910N DIRECT
DIGITAL CONTROL SYSTEMS]].
3.3.1.2
Prerequisite Testing
Each CRACU for which performance testing is dependent upon the completion
of the work covered by Section 15950N HVAC TESTING/ADJUSTING/BALANCING must
have that work completed as a prerequisite to testing work under this
section. Indicate in each field test plan when such prerequisite work is
required.
3.3.1.3
Test Procedure
Indicate in each field test plan the CRACU manufacturer's published
start-up, and field acceptance test procedures. Include in each test plan
a detailed step-by-step procedure for testing automatic controls provided
by the manufacturer.
Procedures shall be structured to test the controls through all modes of
control to confirm that the controls are performing with the intended
sequence of control.
Controllers shall be verified to be properly calibrated and have the proper
set point to provide stable control of their respective equipment.
3.3.1.4
Performance Variables
Each test plan shall list performance variables that are required to be
measured or tested as part of the field test.
Include, in the listed performance variables, requirements indicated on the
CRACU schedules on the design drawings. Manufacturer shall furnish, with
each test procedure, a description of acceptable results that have been
verified.
Manufacturer shall identify the acceptable limits or tolerances within
which each tested performance variable shall acceptably operate.
3.3.1.5
Test Configuration
Plans shall indicate that tests are to be performed for a minimum of four
continuous hours in a wet coil condition. If test period is interrupted,
