Used for establishment of primary reference responses for UT examination of welds. Block contains three side-drilled holes at 1.5″ deep minimum at 3/32″ diameter. Hole locations through the thickness are ¼, ½, and ¾T.
Used for establishment of primary reference responses for UT examination of welds.
Block contains three side-drilled holes at 1.5″ deep minimum at 3/32″ 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.
Dimensions: ½” thick x 6¼” wide x 4.5″ long
Material: A516-70 Steel, bare
Fitted wooden storage case optional.
Special long version for 60/70° transducers or phased array.
The additional length allows for a full skip to the “top” notch. Used for establishment of primary reference responses for UT examination of welds.
