Non-destructive testing -- Image quality of radiographs -- Part 3: Image quality classes for ferrous metals
This standard has been revised by ISO 19232-3:2013.
ISO 19232-3:2004 specifies the minimum image quality values to ensure a uniform radiographic quality. It applies to the two types of image quality indicator as detailed in ISO 19232-1 for wire type image quality indicators and ISO 19232-2 for step/hole type image quality indicators as well as for the two techniques described in ISO 5579. Values are specified for both the basic and improved radiographic techniques specified in ISO 5579 and for ferrous metals.
