This practice covers the design, material grouping classification, and manufacture of wire image quality indicators (IQI) used to indicate the quality of radiologic images. This practice, applicable to X-ray and gamma-ray radiology, covers the use of wire penetrameters as the controlling image quality indicator for the material thickness range from 6.4 to 152 mm [0.25 to 6.0 in.]. The alloy group(s) of the material, the thickness or thickness range of the material, and the applicable IQI's that represent the required IQI thickness(s) and alloy(s) shall be considered when selecting IQI's.
