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 with in 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 (0.5 in). 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.
