The reported value is equivalent to 0.95 p5f at 20% moisture <br />content, the GCL industry standard. <br />~ All tensile testing is performed in the machine direction, with results as minimum average roll values unless otherwise indicated. <br />~ Index Flux with desired distilled water at 5 psi (35 kPa) conrining pressure and 2 psi (15 kPa) head pressure, Reported value is <br />equivalent to 925 gal/acre/day. This fluz value is equivalent to a permeability of 5x10.9 cm/sec. This flux value should not be <br />used far equivalency calculations. A flux test using gradients that represent field conditions must be pertortned to determine <br />equivalency. The last 20 values may be reported from the end of the production date of the supplied GCL.. <br />s Peak value measured at 200 psf (30 kPa) normal stress. Site-specific materials, GCL products, and test conditions must be <br />used to verify internal and interface strength of the proposed design. <br />1350 W.
