DIVISION 1 - GENERAL REQUIREMENTS - IDEAS-EC

A. General: Conduct tests in the presence of the Contracting Officer who shall be given 48 hoursnotice before any test is to be conducted. Provide water and electricity required for the tests.Determine that all dampers, registers, and valves are in a set or full open position.B. Piping: After cleaning, all water piping shall be hydrostatically tested at a pressure equal to 150percent of the total system operating pressure for a period of time sufficient to inspect every jointin the system and in no case less than two hours. No loss of pressure will be allowed. Repairleaks found during tests by rewelding or replacing pipe or fittings. Caulking of joints will not bepermitted. Test concealed and insulated piping in place before covering or concealing.C. Duct Systems: Test all duct systems to prove air tightness. Make tests prior to application of anyexternal insulation before erection of enclosing construction. Pressures for ductwork maintainedduring the tests shall not be less than twice total operating pressure of entire system. Test durationshall be not less than two hours with leakage not to exceed 5 percent of total capacity of system.All audible leaks must be corrected. Make corrections of minor leakage as approved.D. Dampers: Verify that automatic dampers and damper frames are installed level in both directions.Blades shall not touch any adjacent materials throughout full travel by the blades. Verify thatdamper and damper frames are installed so there is no torsion or twist in the frame to preventsmooth operation of the damper. Adjust the linkage of the automatic damper to the air flowquantities shown. Check all automatic dampers in normal operation to verify proper operation.Verify that the return, relief air, and fresh air intake dampers operate as designed to producedesired room comfort.E. Equipment Tests: Upon completion of installation, but before applying power to any operatingequipment or package control system, obtain the services of respective manufacturer'srepresentative to inspect and witness trial runs of equipment. Inspection shall include alignment,direction of rotation, initial lubrication, rpm, voltage, amperage, and nameplate data.3 .4 BALANCINGA. Balance water piping systems to produce water quantities as shown with all manual and automaticcontrol valves open.B. Balance duct system to produce air quantities within 5 percent of the indicated.3 .5 PERFORMANCE TESTSA. After cleaning, pressure and other tests, and adjusting and balancing are complete, each systemshall be performance tested as a whole to verify all items perform as integral parts of the system,and temperatures and conditions are evenly controlled throughout the building. Make correctionsand adjustments as required to produce the conditions indicated.PART 4MEASUREMENT AND PAYMENT4 .1 TESTING, ADJUSTING, AND BALANCING OF H&V SYSTEMSA.
