Product Information
Block contains three side-drilled holes at 1.5 deep minimum at 3/32 diameter (½ and ¾” blocks), 1/8” diameter (1½ block) and 3/16” diameter (3” block). 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.
