<br />' shipment is not covered by the testing. Such testing <br />shall include data on the melt index (ASTM D-1238), <br />density (ASTM D-1504), tensile and elongation (ASTM D- <br />638), thickness {ASTM D-1593), and carbon black content <br />(ASTM D-1603). <br />The test data shall be referenced to a shipment <br />number. Upon placement, the Contractor shall indicate by <br />a plan the exact location at which the liner shipment is <br />' installed. <br />The Contractor shall be responsible for providing <br />his own quality control personnel and testing equipment. <br />' The Engineer will perform his own testing independent of <br />the Contractor's testing. At the end of each shift, the <br />Contractor shall submit to the Engineer a wrif.ten notice <br />indicating the areas of installation completed during <br />that shift. <br />1 <br />Field quality control testing shall involve both <br />' nondestructive and destructive testing. The <br />nondestructive testing shall determine "watertightness" <br />of the seam, whereas the destructive testing shall be <br />based on the ASTM D-638 test method. <br />Destructive testing shall be performed on dumb-bells <br />cut with the seam centrally located within the test <br />specimen. Both shear and peel testing shall be performed. <br />A sample seam shall be made twice during each shift <br />with each seaming machine. Samples from the weld shall be <br />' tested in peel in the field, and no seaming equipment may <br />start work until the sample weld has been approved. <br />Backup samples shall be tested in shear in an approved <br />laboratory for record purposes. <br />t <br />ra-z4 <br />J <br />
