7.3.4 Testing and Field Insoection <br />• The Contractor shall provide the Engineer with a copy <br />of the manufacturer's quality control testing for each shipment <br />or partial shipment of liner if the entire shipment is not <br />covered by the testing. Such testing shall include data on the <br />melt index (ASTM D-1238), density (ASTM D-1504), tensile and <br />elongation (ASTM D-638), thickness (ASTM D-1593), and carbon <br />black content (ASTM D-1603). <br />The test data shall be referenced to a shipment number. <br />Upon placement, the Contractor shall indicate Iby a plan the <br />exact location at which the liner shipment is installed. <br />The Contractor shall be responsible for providing his <br />own quality control personnel and testing equipment. The <br />Engineer will perform his own testing independent of the <br />Contractor's testing. At the end of each shift, the Contractor <br />shall submit to the Engineer a written notice indicating the <br />• 1 <br />areas of installation completed during that shift. <br />Field quality control testing shall involve both <br />nondestructive and destructive testing. The nondestructive <br />testing shall determine "water tightness" of the seam, whereas <br />the destructive testing shall be based on the ASTM D-638 test <br />method. <br />Destructive testing shall be performed on dumb-bells cut <br />with the seam centrally located within the test specimen. Both <br />shear and peel testing shall be performed. <br />A visual examination of all seams shall be performed. <br />Any suspect areas, breaks, or holes in the weld shall be <br />recorded and marked for repair. The Engineer reserves the right <br />to reject any weld which in his sole opinion does not meet the <br />• intent of this Specification. <br />36 <br />
