PH Tool ASTM Distance Amplitude Set of 19

Set of nineteen flat-bottom hole blocks used to determine the relationship between metal travel distance (MTD) and signal amplitude.

All blocks have the same size flat-bottom hole and varying MTD. Hole diameter must be specified when ordering (3/64”, 5/64” or 8/64”). In accordance with ASTM E127. Includes our NIST traceable certification report, ultrasonic inspection report and response plot, and the certified material test report.

*–NEW OPTION–* to purchase “Guaranteed Set” meeting +2dB / -3 dB acceptance criteria.

In 2020, a new version of ASTM E127 (E127-19) was released that rolled in all requirements previously found under E428 and E1158. All materials are now encompassed under E127, and the new version of the spec also introduced the option to order sets meeting specific acceptance criteria. If you’d like to purchase a set that is guaranteed to meet the S2 Supplementary Requirements for Distance Amplitude, please be sure to indicate this by selecting the option above. By doing so, you will ensure that no block in your set deviates from the best-fit trend line by more than +2 dB / -3 dB. We will also add tolerance bars to the ultrasonic response plot for a visual representation of this acceptance criteria.
