ASTM DISTANCE AMPLITUDE BLOCK SET OF 19

Blocks for ASTM E428 Distance Amplitude Calibration Set of 19 flat-bottom hole blocks for measuring the relationship between signal amplitude and metal travel distance (MTD). The flat-bottom holes on every block are the same size, but the MTD varies. When ordering, the hole diameter (3/64", 5/64", or 8/64") must be mentioned. conforming to ASTM E428. includes the certified material test report, Tactic Inc.'s ultrasonic inspection report and response plot, and our NIST traceable dimensional certification report. As mandated by ASTM E127, Section 11, take note that we conduct block characterization using a 5.0 MHz quartz transducer.
