Standard Practice for Fabrication and Control of Flat Bottomed Hole Ultrasonic Standard Reference Blocks

Importancia y uso:

5.1 Standard reference block sets per 4.1 fabricated in accordance with this practice will exhibit specific area-amplitude and distance amplitude relationships only with an immersion test at 5 MHz using the search unit, test instrument, and test parameters described in this practice. Comparison tests at other frequencies or with uncalibrated instruments will not necessarily give the same relationships shown in this practice. See Ref (1)5 for area-amplitude limitations at other frequencies and transducer diameters. Also see Ref (2) for cautions regarding use of standard blocks for test standardizations.

5.2 Reference standards fabricated per 4.2 may utilize the fabrication and verification techniques herein. Due to the variable nature of non-standard blocks, the details should be agreed upon in the ordering documents.
