D. Lining Inspection: <br /> 1. All ductile iron pipe and fitting linings shall be checked for <br /> thickness using a magnetic film thickness gauge. The <br /> thickness testing shall be done using the method outlined <br /> SSPC-PA-2 film thickness rating. <br /> 2. The interior lining of all pipe and fittings shall be tested for <br /> pinholes with a nondestructive 2,500-volt test. <br /> 3. Each pipe joint and fitting shall be marked with the date of <br /> application of the lining system and with its numerical <br /> sequence of application on that date. <br /> E. Certification of Lining Inspection: The pipe or fitting manufacturer <br /> must supply a certificate attesting to the fact that the applicator <br /> met the requirements of this specification, and that the material <br /> used was as specified, and that the material was applied as <br /> required by the specification. <br /> F. Repair: Anywhere that the coating is removed purposely or <br /> accidentally, the area shall be cleaned of any rust, grease, and dirt <br /> and re-coated to a minimum dry film as specified for the individual <br /> piece. <br /> G. Encasement: If and when directed by the Engineer of Record and <br /> IRCDUS, a polyethylene encasement shall be provided around <br /> pipe, fittings, and valves. The material, installation, and <br /> workmanship shall conform to applicable sections of AVWVA <br /> Standard Specifications C105/A21.5-99, or latest revision. <br /> Installation methods A or B shall be employed using flat tube <br /> polyethylene. The Contractor shall make provisions to keep the <br /> polyethylene from direct exposure to sunlight prior to installation. <br /> Backfilling following installation shall be completed without delay <br /> to avoid exposure to sunlight. <br /> H. All exposed sewer ductile iron pipe shall be coated (painted) <br /> green per approved manufacturer's Product List. <br /> 4.06 BELL AND SPIGOT CONNECTIONS <br /> Joints in bell and spigot pipe shall be push-on, mechanical, or restrained <br /> joints in accordance with AWWA Standard Specifications C111/A21.11- <br /> 00, or latest revision. Pipe restraints shall also be in accordance with <br /> IRCDUS Standards or as directed by Engineer or IRCDUS. <br /> 4.07 SUBMITTALS <br /> Before starting fabrication of the ductile iron pipe and fittings, the <br /> Contractor shall submit complete detailed working drawings for approval <br /> by the Engineer or IRCDUS. Such drawings shall show the piping layouts <br /> 4 - 3 <br /> a,3.E . A4_ <br />
