Let us start with the Practices about IQIs (Image Quality Indicator):
E746 Standard Practice for Determining Relative Image Quality Response of Industrial Radiographic Imaging Systems
E747 Standard Practice for Design, Manufacture and Material Grouping Classification of Wire Image Quality Indicators (IQI) Used for Radiology
E1025 Standard Practice for Design, Manufacture, and Material Grouping Classification of Hole-Type Image Quality Indicators (IQI) Used for Radiology
E1647 Standard Practice for Determining Contrast Sensitivity in Radioscopy
E1817 Standard Practice for Controlling Quality of Radiological Examination by Using Representative Quality Indicators (RQIs)
E2002 Standard Practice for Determining Total Image Unsharpness in Radiology
E1735 Standard Practice for Determining Relative Image Quality Response of Industrial Radiographic Imaging Systems from 4 to 25 MeV with change in title from
test method to
practice in Nov 2019 ballot.
All these standards does not only describe the IQI itself, they also give instructions and regulations how to use the IQI within detail, e.g. the Duplex Wire IQI in E2002 has to be
positioned at an angle of approximately 2° to 5° towards the pixel line or column orientation.
Hint: If you read "shall" in an ASTM standard have in your mind that this is mandatory to fullfil the standard; if you read "should" you should do it as described, but it is not mandatory.

Reason: added E1735 due to actual ballot
