IIW-Type 2 Calibration Test Block (Metric Version) STAINLESS STEEL 304
IIW type blocks are used to calibrate instruments for both angle beam and normal incident inspections. Some of their uses include setting metal-distance and sensitivity settings, determining the sound exit point and refracted angle of angle beam transducers, and evaluating depth resolution of normal beam inspection setups. Instructions on using the IIW type blocks can be found in the annex of American Society for Testing and Materials Standard E164, Standard Practice for Ultrasonic Contact Examination of Weldments.
A modified version of the original IIW-Type 1 design in a metric version. Includes a 50mm radius x 5.0mm deep cut-out superposed on the 100mm radius for distance calibration. Also includes 1.0mm, 2.0mm and 3.0mm through holes for sensitivity testing or surface wave inspection, and distance calibration marks to the 50mm hole. NDE FLAW design based on International Institute of Welding, ASTM E164 and U.S. Air Force NDI Manual T.O. 33B-1-1 specifications.
