6.2.5.5 Field Testing <br />The two 1 -inch wide samples shall be tested in the field for peel adhesion and <br />bonded seam strength (shear) by the Contractor/Liner Subcontractor, and shall not <br />fail in the seam, but shall have a film tearing bond (FTB). If one or both of the <br />samples fails in either peel or shear, the Contractor/Liner Subcontractor can, at <br />his/her discretion, (1) reconstruct or cap strip the seam between passed test <br />locations, or (2) take two additional test samples 10 feet on either side of the point <br />of the failed test and repeat this procedure. If the second test passes, the <br />Contractor/Liner Subcontractor shall reconstruct or cap strip the same between the <br />two passed test locations. If subsequent tests fail, the procedure is repeated until <br />the length of the poor quality seam is established. Repeated failures indicate that <br />either the seaming equipment and/or operator is not performing properly, and <br />appropriate action shall be taken. <br />6.2.5.6 Laboratory Testing <br />Once the field tests have passed, a sample shall be recovered from between <br />passing field sample locations for testing by the GAI approved Independent <br />Testing Laboratory. Destructive test samples shall be packaged and shipped to <br />the laboratory by the Geotechnical CQA Monitors and will be'handled in a <br />manner which will not damage the test sample. The Construction Manager will <br />be responsible for storing the archive samples. <br />All specimens of a°field weld sample tested by the Independent Testing <br />Laboratory shall pass. If any specimen fails, the entire sample shall be considered <br />as a failure, andthe4ield weld shall be rejected. In this event; the Feld seam(s) <br />shall be rejected as being nonconformant with the Specifications, and corrective <br />measures shall be implemented. <br />For destructive samples that have failed, corrective measures shall include a rerun <br />of the weld test using the same sample. If the second test passes, the <br />Geotechnical CQA Monitor may assume an error was made ,in:the f rst..test nand <br />the field seam may be accepted. If the second test fails, the Contractor/Liner <br />Subcontractor shall reconstruct or cap strip the field seam between any two <br />previous passed seam locations, which include the failed seam or shall go on both <br />sides of the failed seam location (10 -feet minimum), take another sample each <br />side and test both in the independent laboratory. <br />If both samples pass, the Contractor/Liner Subcontractor shall reconstruct or cap <br />strip the field seam between the two passing locations. If either fails, the <br />Contractor/Liner Subcontractor shall repeat the process of taking samples for <br />testing by the Independent Testing Laboratory. In all cases, acceptable field <br />seams must be bounded by two passed test locations. In cases involving more <br />than 50 feet of reconstructed or cap stripped seam, the reconstructed or cap <br />stripped seam shall also be tested.
