'In IFR ITEMS Number or amount in place upon completion of work, - 8 - It is recommended that the Specification for the Air Test consist of two parts- The Presumptive Test and the Acceptance Test. THE PRESUMPTIVE TEST The contractor may low pressure air test the line before backfilling the trench to aid the contractor in checking the installation for any defects and proper workmanship. This test is at the option of the contractor THE ACCEPTANCE TEST The 4:intracto► shall test the line as prescribed in the specifications by the engineer o• agency after the backfilling has been completed. RECOMMENDED AIR TEST. The contractor shall furnish all facilities and personnel for conducting the test under the observation of the Engineers. The equipment and personnel sholl be subject to the app,oval of the Engineers The c.ontracto, shall clean the line before proceeding with the air test. All debris shall be removed at the first manhole where its presence is noted Irr the event cemented or wedged debris or a damaged pipe shall prevent cleaning the contractor shall emove the obstruction The pipe or sections of pipe to be tested should be wetted before the air test is started Immediately following the pipe cleaning and wettings, the pipe shall be tested with low pressure air. Ai shall be slowly supplied to the plugged pipe installation until the internal air pressa,e reaches 4.0 pounds per square inch greater than the average back p,essure of any g ound water that may submerge the pipe At least two minutes shall be allowed fo, tempt atwe stobilization before proceeding further. The rate of air loss shall then be dctermined by measuring the time interval required for the internal pressure to dec,eose f,om 3.5 to 2.5 pounds pe° square inch greater than the average back pressure of uny ground water that may submerge the pipe . The pipeline shall be considered acceptable when tested at an average pressure of 3.0 pounds per squa,e inch greater than the average back pressure of any ground water that may subrne,ge the pipe when the section under test does not lose air at a rate greater than 0.003 cubic feet per minute per square foot of internal pipe area except that the minimum allowable rate of loss for the section shall not be less than 2 cubic feet per minute The requirements of this specification shall be considered satisfied if, during the time as computed according to the attached page entitled "Recommended Procedure for Conducting Acceptance Test" the pressure in the pipe line does not drop more than one p.s i. below the initial pressure of 3 .5 p.s. i greater than the average back pressure of any ground water head that may submerge the (pipe) line Acceptance Test shall be made for each first section of line constructed, for every ist reach of line installed where a new sewer crew is used, or wherever the Engineer may direct. The contractor shall not p,oceed with any construction until the prerequisite of meeting the successful installation of each section is made, as mentioned above, to qualify the crew and/or material . If the pipe instaliation fails to meet these requirements, the contractor shall determine at his own expense the source or sources of leakage, and he shall repair or replace all defective materials or wo kmanship. The completed pipe installation shall meet the requirements of this test, o• the alternate water exfiltration ar infiltration test beforr' being considered acceptable SAFETY PROVISIONS, The plugs must be fi.rml secured and cage should be exercised in their removal (The total force on a 12" plug ct 4 0 p s.4„ is over 450 pounds,) Ca,e must be exercised in not loading the sewer Fine with the full pressure of the compressor , Keep men out of manholes until the pressure has been released. If weter leaks into the line after the plugs are installed and floods the air inlet and the needle on the ah, pressure gage indicates zero then possibly the water column has balanced the air pressure in this instance and care is necessary in eleasing the pressure. If testing below ground water level; inject the air at the upper plug and/or, turn the inlet up as with a water test apparatus Reference- Low Pressure Air Test for Sanitary Sewers by Roy E.
