Abstract
An ultrasonic test standard is formed by a metal block having a unique shape incorporating an arcuate surface and a series of reflectors that enable discreet instrument measurement verifications in a relatively small area. This calibration block, though relatively small and light in weight, will perform all of the functions of a standard IIW (International Institute of Welding) type block and additional functions.
