SECTION 4 – SANITARY 68 4.) Proving rings shall be provided to check the mandrel. Drawings of mandrels with complete dimensions shall be furnished to the City upon request for each diameter and specification of pipe. 4-4.2 (d) FORCE MAIN PRESSURE TEST (PVC AND DUCTILE IRON PIPE) 1.) Pressure pipe shall be subjected to hydrostatic pressure test per AWWA C600 at twice the working pressure of the proposed pipe. Test each section by means of a pump connected thereto. All air shall be expelled from the pipe by satisfactory means. 2.) Test all pipe after backfilling and prior to pavement placement. Pressure tests shall not be less than two (2) hours in duration. Leakage is defined as the quantity of water required to maintain a pressure within five (5) psi of the specified test pressure, after air has been expelled and the pipe filled with water. Leakage permitted shall not exceed ten (10) gallons per inch of diameter per mile of pipe per day at the specified pressure. 4-4.2 (e) FORCE MAIN PRESSURE TEST (HDPE PIPE) 1.) Butt Fusion Testing: Butt fusion testing shall be conducted at least once every day that butt fusions are made. The first fusion of the day shall be a trial fusion. The trial fusion shall be allowed to cool completely to ambient temperature, and then fusion test straps shall be cut out per ASTM D 2657. The test strap shall be a minimum of twelve (12) inches, or thirty (30) times the wall thickness, in length with the fusion in the center and shall be a minimum of one (1)inch, or one and one-half (1.50) times the wall thickness, in width. Bend the test strap until the ends of the strap touch. If the fusion fails at the joint, a new trial fusion shall be made, cooled completely, and tested. Butt fusion of pipe to be installed shall not commence until a trial fusion has passed the bent strap test. 2.) Pressure Testing: Pressure testing of the HDPE pipe shall be conducted at twice the working pressure of the proposed sanitary force main for at least two (2) hours according to Technical Note 802 – Leak Testing, July 2006, from Performance Pipe and per the manufacturer’s recommendations. A copy of Technical Note 802 may be obtained at www.performancepipe.com. Pressure testing shall be hydrostatic only. Pneumatic pressure testing shall not be used. 3.) Test Duration: The maximum test duration is eight (8) hours including time to pressurize the pipe, time for initial expansion, time for the test at test pressure, and time to depressurize the segment of pipe being tested. If the test is not completed due to leakage, equipment failure, or for any other reason, depressurize the test section completely, and allow for it to relax for at least eight (8) hours before pressurizing the test section again. 4.) The hydrostatic test as described in Technical Note 802 is summarized as follows: Pipe Segment Filling: Fill the test section completely with water from the lowest possible point. Ensure that there is no air trapped in the test section by utilizing vents to expel the air. Initial Expansion: Gradually pressurize the test section to test pressure and maintain test pressure for three (3) hours. During the initial expansion phase polyethylene pipe will expand
