Guide to designs of IIW-type blocks

Abstract

This guide describes 11 designs of IIW-type ultrasonic calibration blocks. The designation ‘IIW-type block’ specifically recognizes that these designs are different from the authentic International Institute of Welding ‘IIW Calibration Block 1’. In order to avoid introducing new nomenclature, the designs are given as numbered examples. The designs cited are generally made of steel.
