TESTING AND BALANCING HEATING AND VENTILATING SYSTEMS
selections of data (water and air quantities and air motion) recorded in the Certified
Report.
Points and areas for recheck will be selected by the Engineer.
Measurement and test procedures shall be the same as approved by the Engineer for
the Work forming basis of report.
Selections for recheck (specific plus random), in general, will not exceed 15 percent
of the total number tabulated in the report.
Retests: If random tests elicit a measured flow deviation of ten percent or more
from that recorded in the Balance Report listings, at ten percent or more of the
rechecked selections, the report shall be automatically rejected. In the event the
report is rejected, readjust all systems and re-test. Submit new data recorded, new
Balance Reports and make new inspection tests, all at no additional cost to the
Owner.
Marking of Settings: Following final acceptance of Balance Reports by the
Engineer, permanently mark the settings of all valves, splitters, dampers, and other
adjustment devices so that adjustment can be restored if disturbed at any time. Do
not mark devices until after final acceptance.
