Second value represents minimum average roll value. <br />3 Carbon Black dispersion (only near spherical agglomerates) for 10 different views: <br />- 9 in Categories 1 or 2 and 1 in Category 3. <br />4 Machine direction (MD) and cross machine direction (XMD) average values should be on the basis of five test specimens in each <br />direction. <br />5 Seam strength refers to both fusion and extruded seams for HDPE to HDPE welds. Refer also to GRI GM 19. <br />6 If peel strength exceeds ultimate tensile strength of the sheet but the sample fails FTB, the test will be considered a pass. <br />2.2 SEAMING AND TESTING EQUIPMENT <br />A. Seaming <br />1. Approved field seaming processes are hot shoe double fusion <br />welding and extrusion welding, when approved by Design <br />Engineer. Use double fusion welding as primary method of <br />seaming adjacent field panels. <br />2. Contractor shall maintain on -site a minimum of two spare operable <br />seaming apparatuses. <br />3. Seaming equipment shall not damage the geosynthetic. <br />Rio Grande Silver Tailings Evaporation Pond 02620 -9 Geosynthetic Liner <br />August 2011 02620 <br />
