TESTING AND BALANCING HEATING AND VENTILATING SYSTEMS
1.2 SUBMITTALS TO THE ENGINEER
A.
B.
Submit the name of the proposed testing organization to the Engineer for approval
within 90 days after Contract award.
Provide all results of all required tests for the Engineer's approval.
1.3 AGENDA
A.
Preliminary Report: Review Drawings and Specifications prior to the installation of
any of the affected systems, and submit a written report to the Engineer indicating
any deficiencies in the system that would preclude the proper adjusting, balancing,
and testing of the systems.
Submit an agenda for approval by the Engineer prior to start of testing and
balancing work. The agenda shall include the following:
1. A complete listing of all air and water flow and air terminal measurements to
be performed.
2. Specific test procedures and parameters for determining specified quantities,
e.g., flow, drafts, etc., from the actual field measurements to establish
compliance with the Contract Documents.
3. Samples of forms showing applications of procedures and calculations to
typical systems.
Advise the Engineer in advance when the testing will begin so that the testing
procedure and techniques can be evaluated and approved or modified.
Procedure Reporting: Specific test procedures for measuring air quantities at
terminals shall specify type of instrument to be used, method of instrument
application (by sketch), and factors used.

2.1 MATERIALS
A.
Not applicable in this Section.
PART 3 - EXECUTION
3.1 PROCEDURES AND INSTRUMENTS - GENERAL
A.
B.
Requirements: Adjust all systems and components to perform as required by the
Drawings and Specifications.
Test Duration: Perform operating tests of heating coils, fans and other equipment
no less than a four-hour duration after stabilized operating conditions have been
established. Base capacities on temperatures and air and water quantities measured
during such tests.
Instrumentation: Use methods of application of instrumentation in accordance with
the approved agenda.
Use only instruments used for measurements that are accurate, and calibrated within
6 months of the testing with calibration histories for each instrument available for
examination. Have each test instrument calibrated by a laboratory approved by the
Engineer or by the manufacturer. The Engineer has the right to request instrument
recalibration, or the use of other instruments and test methodology, where accuracy
of readings is questionable.
