ASTM Blocks

These ASTM Blocks are used to evaluate the sensitivity, surface entry resolution, and horizontal/vertical linearity characteristics of UT equipment. Each Block is Sold Separately

ASTM E317 Figure 1 & Figure 6

ASTME317 Resolution Block, Figure 6 is used for evaluating the resolution characteristics of ultrasonic pulse-echo systems. It contains six 3/64″ diameter flat-bottom holes.

ASTM E317 block, Figure 1 is used for evaluating horizontal and vertical linearity characteristics of ultrasonic pulse-echo systems. It contains two 3/64″ diameter side-drilled holes.
