Designation:E141609Standard Test Method forRadioscopic Examination of Weldments1This standard is issued under the fixed designation E1416;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 test method covers a uniform procedure for radio-scopic examination of weldments.Requirements expressed inthis test method are intended to control the quality of theradioscopic images and are not intended for controlling accept-ability or quality of welds.1.2 This test method applies only to the use of equipmentfor radioscopic examination in which the image is finallypresented on a display screen(monitor)for operator evalua-tion.The examination may be recorded for later review.It doesnot apply to fully automated systems where evaluation isautomatically performed by computer.1.3 The radioscopic extent,the quality level,and the accep-tance criteria to be applied shall be specified in the contract,purchase order,product specification,or drawings.1.4 This test method can be used for the detection ofdiscontinuities.This test method also facilitates the examina-tion of a weld from several directions,such as perpendicular tothe weld surface and along both weld bevel angles.Theradioscopic techniques described in this test method provideadequate assurance for defect detectability;however,it isrecognized that,for special applications,specific techniquesusing more stringent requirements may be needed to provideadditional detection capability.The use of specific radioscopictechniques shall be agreed upon between purchaser and sup-plier.1.5 The values stated in inch-pound units are to be regardedas the standard.The SI units given in parentheses are forinformation only.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.Specific precau-tionary statements are given in Section 7.2.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 RadiologyE1255 Practice for RadioscopyE1316 Terminology for Nondestructive ExaminationsE1453 Guide for Storage of Magnetic Tape Media thatContains Analog or Digital Radioscopic DataE1475 Guide for Data Fields for Computerized Transfer ofDigital Radiological Examination DataE1647 Practice for Determining Contrast Sensitivity in Ra-diologyE1742 Practice for Radiographic Examination2.2 ASNT Standards:3ASNT Recommended Practice No.SNT-TC-1A PersonnelQualification and Certification in Nondestructive TestingANSI/ASNT CP-189-ASNT Standard for Qualification andCertification of Nondestructive Testing Personnel2.3 National Aerospace Standard:4NAS 410 Certification and Qualification of NondestructiveTest Personnel3.Terminology3.1 Definitions:3.1.1 Definitions of terms applicable to this test method maybe found in Terminology E1316.1This test method is under the jurisdiction of ASTM Committee E07 onNondestructive Testing and is the direct responsibility of Subcommittee E07.01 onRadiology(X and Gamma)Method.Current edition approved July 1,2009.Published August 2009.Originallyapproved in 1991.Last previous edition approved in 2004 as E1416-04.DOI:10.1520/E1416-09.2For 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 TheAmerican Society for Nondestructive Testing(ASNT),P.O.Box 28518,1711 Arlingate Ln.,Columbus,OH 43228-0518.4Available from Aerospace Industries Association of America,Inc.(AIA),1000Wilson Blvd.,Suite 1700,Arlington,VA22209-3928,http:/www.aia-aerospace.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Apparatus4.1 Radiation Source(X-ray or Gamma-ray)Selection ofthe appropriate source is dependent upon variables regardingthe weld being examined,such as material composition andthickness.The suitability of the source shall be demonstratedby attainment of the required image quality and compliancewith all other requirements stipulated herein.Guidance on theselection of the radiation source may be found in Guide E1000and Practice E1255.4.2 Manipulation SystemSelection of the appropriate ma-nipulation system(where app
