Other materials maybe used in accordance with 7.3.4.1.2 The IQI consists of sets of wires arranged in order ofincreasing diameter. The diameter size
10、s specified in Table 1 areestablished from a consecutive series of numbers taken ingeneral from the ISO/R 10 series. 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 alte

International users ofthese type IQI standards who prefer the use of EN 462-1 fortheir particular applications should specify such alternateprovisions within separate contractual arrange
18、ments from thisstandard.5. Image Quality Indicator (IQI) Procurement5.1 When selecting IQIs for procurement, the followingfactors should be considered:5.1.1 Determine the alloy group(s) of the material to beexamined.5.1.2 Determine the thickness or thickness range of thematerial(s) to be examined.5.
19、1.3 Select the applicable IQIs that represent the requiredIQI thickness(s) and alloy(s).6. Image Quality Levels6.1 The quality level required using wire penetrametersshall be equivalent to the 2-2T level of Practice E1025 forhole-type IQIs unless a higher or lower quality level is agreedupon between
20、 purchaser and supplier. Table 4provides a list ofvarious hole-type IQIs and the diameter of wires of corre-sponding equivalent penetrameter sensitivity (EPS) with theapplicable 1T, 2T, and 4T holes in the IQI. This table can beused for determining 1T, 2T, and 4T quality levels. AppendixX1 gives the
21、 equation for calculating other equivalencies ifneeded.6.2 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
22、 impor-tant.7. Material Groups7.1 General:7.1.1 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 heavymetals.7.1.2 The light metal groups, magnesium (Mg), aluminum(Al), and titanium
23、(Ti) are identified 03, 02, and 01 respec-tively, for their predominant alloying constituent.The materialsare listed in order of increasing radiation absorption.7.1.3 The heavy metal groups, steel, copper-base, nickel-base, and kindred alloys are identified 1 through 5. Thematerials increase in radi
24、ation absorption with increasingnumerical designation.7.1.4 Common trade names or alloy designations have beenused for clarification of the pertinent materials.7.1.5 The materials from which the IQI for the group are tobe made are designated in each case and these IQIs areapplicable for all material
25、s listed in that group. In addition, anygroup IQI may be used for any material with a higher groupnumber, provided the applicable quality level is maintained.7.2 Materials Groups:7.2.1 Materials Group 01:7.2.1.1 Image quality indicators (IQIs) shall be made oftitanium or titanium shall be the predom
