Description

Used for establishment of primary reference responses for UT examination of welds. Block contains three side-drilled holes at 1.5 deep minimum at 1/4 diameter. Hole locations through the thickness are ¼, ½, and ¾T. Also contains two EDM notches measuring 2%T deep x 1/4 max wide x 1.0 long min. In accordance with ASME Sec V Art. 4 Fig. T-434.2.1.

ASME Basic Calibration Blocks are intended to be representative of actual components, and therefore do not have the smooth scanning surfaces found on most general-purpose test blocks like the IIW or DSC. Instead, our Basic Calibration Blocks are media blasted on all surfaces to create a rough surface texture that is more characteristic of real-world inspection conditions.

Thicker blocks available upon request. For handling purposes, 5 Thick Blocks and above get lifting lugs or handles welded on both ends.

  • Dimensions: 5 thick x 6¼ wide x 15 long
  • Note: This block weighs 135 pounds
  • No hardwood case available at this time.
