1 Designation: E 747 97An American National StandardStandard Practice forDesign, Manufacture and Material grouping Classification ofWire Image Quality Indicators (IQI) Used for Radiology1 This Standard is issued under the fixed designation E 747; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or This practice2covers the design , Material groupingclassification, and Manufacture of wire image quality indica-tors (IQI) used to indicate the quality of radiologic This Practice is applicable to X-ray and This Practice covers the use of wire penetrameters as thecontrolling image quality indicator for the Material thicknessrange from to 152 mm ( to in.)

5 The IQI shall be fabricatedin accordance with the requirements specified in Figs. 1-8 andTables 1-3. IQIs previously manufactured to the requirementsof Annex A1 may be used as an alternate provided all otherrequirements of this Practice are Image quality indicator (IQI) designs other than thoseshown in Figs. 1-8 and Annex A1 are permitted by contractualagreement. If an IQI set as listed in Table 1 or Annex A1 ismodified in size, it must contain the grade number, set identity,and essential wire. It must also contain two additional wiresthat are the next size larger and the next size smaller asspecified in the applicable set listed in Table Each set must be identified using letters and numbersmade of industrial grade lead or of a Material of similarradiographic density.

Image Quality The quality level required using wire penetrametersshall be equivalent to the 2-2T level of Practice E 1025 forhole-type IQI s unless a higher or lower quality level is agreedupon between purchaser and supplier. Table 4 provides a list ofvarious hole-type IQI s and the diameter of wires of corre-sponding equivalent penetrameter sensitivity (EPS) with theapplicable 1T, 2T, and 4T holes in the IQI.

7 This table can beused for determining 1T, 2T, and 4T quality levels. AppendixX1 gives the equation for calculating other equivalencies In specifying quality levels, the contract, purchase order,product specification, or drawing should clearly indicate thethickness of Material to which the quality level applies. Carefulconsideration of required quality levels is particularly Material Materials have been designated in eight groups basedon their radiographic absorption characteristics: groups 03, 02,and 01 for light metals and groups 1 through 5 for The light metal groups, magnesium (Mg), aluminum(Al), and titanium (Ti) are identified 03, 02, and 01 respec-tively, for their predominant alloying constituent.

8 The materialsare listed in order of increasing radiation The heavy metal groups, steel, copper-base, nickel-base, and kindred alloys are identified 1 through 5. Thematerials increase in radiation absorption with increasingnumerical Common trade names or alloy designations have beenTABLE 3 Wire Diameter Tolerances, (in.)Wire Diameter (d), , <d# <d# <d# <d# <d# <d# 1 Set A/Alternate 1E 7472 COPYRIGHT American Society for Testing and MaterialsLicensed by Information Handling ServicesCOPYRIGHT American Society for Testing and MaterialsLicensed by Information Handling Servicesused for clarification of the pertinent The materials from which the IQI for the group are tobe made are designated in each case and these IQI s areapplicable for all materials listed in that group.
