Designation:E195504(Reapproved 2014)Standard Radiographic Examination forSoundness of Welds in Steel by Comparison to GradedASTM E390 Reference Radiographs1This standard is issued under the fixed designation E1955;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 standard covers requirements for radiographicexamination for soundness of welds in fabricated steel bycomparison to selected severity levels of Reference Radio-graphs E390,Vol II.The base material varies from greater than0.25 to 3 in.(6.476 mm)inclusive in thickness.Volume II isapplicable.This standard is not suitable for shipyard use.NOTE1This standard was adopted to replace Mil-Std.1264-B entitled“Radiographic Inspection For Soundness of Welds In Steel By Compari-son To Graded ASTM E390 Reference Radiographs,”dated 18 January,1989.This standard is intended to be used for the same applications as thedocument which it replaced.Users should carefully review its require-ments when considering the standards use for new and/or differentapplications.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 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.2.Referenced Documents2.1 ASTM Standards:2E390 Reference Radiographs for Steel Fusion WeldsE1316 Terminology for Nondestructive Examinations2.2 Military Standards:NAS-410 Certification and Qualification of NondestructiveTest Personnel32.3 ASNT Standards:4SNT-TC-1A Recommended Practice for Personnel Qualifi-cation and Certification in Nondestructive TestingANSI/ASNT-CP-189 Standard for Qualification and Certifi-cation of Nondestructive Testing Personnel2.4 American Welding Society Standards:AWS D 1.1 Structural Welding Code Steel52.5 American Petroleum Institute Standards:API STD-1104 Standard for Welding Pipelines and RelatedFacilities62.6 Adjuncts:Reference Radiographs for Steel Fusion Welds:Volume II,Thickness Over14to 3 in.(6.4 to 76 mm),incl73.Terminology3.1 DefinitionsFor definitions of terms used in thisdocument,see Terminology E1316.3.2 Definitions of Terms Specific to This Standard:3.2.1 gradeswelds shall be designated Grades I,II,III,orIV as shown in Table 1.AGrade I weld would contain the leastor smallest discontinuities,or both,and a Grade IV weld wouldcontain the largest or most numerous discontinuities,or both.3.2.2 examination lotan examination lot shall consist ofall welds of a specific design and size produced at one facilityby the same personnel and production technique,and submit-ted for examination at one time.1This standard is under the jurisdiction of ASTM Committee E07 on Nonde-structive Testing and is the direct responsibility of Subcommittee E07.02 onReference Radiological Images.Current edition approved Oct.1,2014.Published November 2014.Originallyapproved in 1998.Last previous edition approved in 2009 as E1955-04(2009).DOI:10.1520/E1955-04R14.2For 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 Aerospace Industries Association of America,Inc.(AIA),1000Wilson Blvd.,Suite 1700,Arlington,VA22209-3928,http:/www.aia-aerospace.org.4Available fromAmerican Society for Nondestructive Testing(ASNT),P.O.Box28518,1711 Arlingate Ln.,Columbus,OH 43228-0518,http:/www.asnt.org.5Available from American Welding Society(AWS),550 NW LeJeune Rd.,Miami,FL 33126,http:/www.aws.org.6Available from American Petroleum Institute(API),1220 L.St.,NW,Washington,DC 20005-4070,http:/www.api.org.7Available from ASTM International Headquarters.Order Adjunct No.RRE039002.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Significance and Use4.1 This standard can be used to establish acceptancecriteria for weld soundness based on the procedures andreference radiographs of ASTM E390.The grades specified inthis standard,while applicable for general examination use forthe materials and thicknesses indicated,may not be suitable forall applications.5.General Practices5.1 Personnel QualificationNondestructive testing(NDT)personnel shall be qualified in accordance with a nationally orinternationally recognized NDT personnel qualification prac-tice or standard such as ANSI/ASNT-CP-189,SNT-TC-1A,NAS-410,or a similar document.The pract
