Designation:E269810Standard Practice forRadiological Examination Using Digital Detector Arrays1This standard is issued under the fixed designation E2698;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()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice establishes the minimum requirements forradiological examination for metallic and nonmetallic materialusing a digital detector array(DDA)system.1.2 The requirements in this practice are intended to controlthe quality of radiologic images and are not intended toestablish acceptance criteria for parts or materials.1.3 This practice covers the radiologic examination withDDAs including DDAs described in Practice E2597 such as adevice that contains a photoconductor attached to a Thin FilmTransistor(TFT)read out structure,a device that has aphosphor coupled directly to an amorphous silicon read-outstructure,and devices where a phosphor is coupled to a CMOS(Complementary metaloxidesemiconductor)array,a LinearDetector Array(LDA)or a CCD(charge coupled device)crystalline silicon read-out structure.1.4 The DDA shall be selected for an NDT applicationbased on knowledge of the technology described in GuideE2736,and of the selected DDA properties provided by themanufacturer in accordance with Practice E2597.1.5 The requirements of this practice and Practice E2737shall be used together and both be approved by the CEO Level3 in Radiography before inspection of production hardware.The requirements of Practice E2737 will provide the baselineevaluation and long term stability test procedures for the DDAsystem.1.6 The requirements in this practice shall be used whenplacing a DDA into NDT service and,before being placed intoservice,an established baseline of system qualification shall beperformed in accordance with Practice E2737.1.7 Techniques and applications employed with DDAs arediverse.This practice is not intended to be limiting or restric-tive.Refer to Guides E94,E1000,E2736,Terminology E1316,Practice E747 and E1025,Fed.Std.Nos.21CFR 1020.40 and29 CFR 1910.96 for a list of documents that provide additionalinformation and guidance.2.Referenced Documents2.1 ASTM Standards:2E94 Guide for Radiographic ExaminationE543 Specification for Agencies Performing NondestructiveTestingE747 Practice for Design,Manufacture and Material Group-ing Classification of Wire Image Quality Indicators(IQI)Used for RadiologyE1000 Guide for RadioscopyE1025 Practice for Design,Manufacture,and MaterialGrouping Classification of Hole-Type Image Quality In-dicators(IQI)Used for RadiologyE1316 Terminology for Nondestructive ExaminationsE1647 Practice for Determining Contrast Sensitivity in Ra-diologyE1742 Practice for Radiographic ExaminationE2002 Practice for Determining Total Image Unsharpness inRadiologyE2597 Practice for Manufacturing Characterization of Digi-tal Detector ArraysE2736 Guide for Digital Detector ArraysE2737 Practice for Digital Detector Array PerformanceEvaluation and Long-Term Stability2.2 AWS Documents:3AWSA2.4 Symbols for Welding and Nondestructive Testing2.3 Aerospace Industries Association Document:4NAS 410 Certification&Qualification of NondestructiveTest Personnel2.4 Government Standards:NIST Handbook 114 General Safety Standard for Installa-tions Using Non-medical X-ray and Sealed Gamma RaySources,Energies up to 10 MeV5DoD Contracts any specifications called out on the DoDISS(Department of Defense Index of Specifications and1This practice is under the jurisdiction of ASTM Committee E07 on Nonde-structive Testing and is the direct responsibility of Subcommittee E07.01 onRadiology(X and Gamma)Method.Current edition approved April 15,2010.Published July 2010.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American Welding Society(AWS),550 NW LeJeune Rd.,Miami,FL 33126,http:/www.aws.org.4Available from Aerospace Industries Association of America,Inc.(AIA),1000Wilson Blvd.,Suite 1700,Arlington,VA22209-3928,http:/www.aia-aerospace.org.5Available from National Institute of Standards and Technology(NIST),100Bureau Dr.,Stop 1070,Gaithersburg,MD 20899-1070,http:/www.nist.gov.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Standards)cited in the solicitation.21-CFR-1020.40 Safety Requirements of Cabinet X-raySystems29-CFR-1910.96 Ionizing RadiationNCRP 144 Radiation Protection for Particle AcceleratorFacilitiesSMPTE RP 133 Specifications for Medical Diagnostic Im-aging Test Pattern for Television Monitors and Hard-CopyRecording Cameras3.Terminology3.1 Definitions relating to the radiological examination,which appea
