ASTM Distance Area Amplitude Block Set of 10 (Inch Version) ASTM E428 Distance Area Amplitude Calibration Blocks Basic set of ten flat-bottom hole blocks used to determine dead zone, sensitivity, distance and area amplitude linearity measurements. In accordance with ASTM E428. Includes our NIST traceable dimensional certification report, ultrasonic inspection report and two response plots from Tactic Inc, and the certified material test report. Note that we use a 5.0 MHz quartz transducer for block characterization as required by ASTM E127, Section 11. Geometry: Set of 10 Contains the following hole diameters and metal travel distances: 3/64" - 3.0" (3-0300), 5/64" - .12" (5-0012), 5/64" - .25" (5-0025), 5/64" - .50" (5-0050), 5/64" - .75" (5-0075), 5/64" - 1.5" (5-0150), 5/64" - 3.0" (5-0300), 5/64" - 6.0" (5-0600), 8/64" - 3.0" (8-0300) and 8/64" - 6.0" (8-0600).
