METHOD DESCRIPTION ASTM D5994 Thickness (mils) Apparatus: Dead-weight dial micrometer with gauge points tapered at an angle of 60° +/- 2e to the horizontal with the tip rounded to a radius of 0.8+/-0.1 mm(0.031+/-0.004 in), with a specified force of 0.56+/-0.05 N (2+/-0.2 oz) Loading Time: 5sec Specimen Size: 4"x 4" 54 min. 63 62 62 61 62'- 61 62 62 61 62 I' 62 il' 61 r1 63 60 min. ave. ASTM D7466 Asperity Height of Textured Geomembrane (mils) Apparatus: Has a dial indicator that travels at least 2.5mm (0.1 in), and a depth gauge with contact point that travels up and down within the setting block with a base dimension of 50 mm x 20 mm (2.0 in x 0.75 in) and a height of 15 mm (0.50). The contact point is 1.3 mm (0.051 in) in diameter with the tip tapered to a point with an extension of 17 mm (0.66 in). Sampling: Ten (10) 3" diameter specimens were cut across the width of the sample in a randomly distributed manner The highest reading from 3 readings were taken per specimen.
