Designation:E132015Standard Reference Radiographs forTitanium Castings1This standard is issued under the fixed designation E1320;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 The reference radiographs provided in the adjunct to thisstandard are reproductions of original radiographs and aresupplied as a means for establishing some of the categories andseverity levels of discontinuities in titanium castings that maybe revealed by radiographic examination.Use of this standardfor the specification or grading of castings requires procure-ment of the adjunct reference radiographs which illustrate thediscontinuity types and severity levels.They should be used inaccordance with contractual specifications.NOTE1The original radiographs produced for Volume I were takenwith X-rays in the range of 110 KV to 220 KV.The original radiographsproduced for Volume II were taken with X-rays in the range of 200 K to340 KV.1.2 These film reference radiographs are not intended toillustrate the types and degrees of discontinuities found intitanium castings when performing digital radiography.Ifperforming digital radiography of titanium castings,refer toDigital Reference Image Standard E2669.1.3 These reference radiographs consist of two volumes.Volume I,described in Table 1,is applicable to a wall thicknessof up to 1 in.(0 to 25.4 mm).Volume II,described in Table 2,is applicable to a wall thickness of over 1 in.to 2 in.(25.4 mmto 50.8 mm).The standard may be used,where there is no otherapplicable standard,for other thicknesses for which agreementhas been reached between purchaser and manufacturer.NOTE2The reference radiographs are not impacted by this revision.There have been no revisions to the adjunct reference radiographs sinceoriginal issue.The adjunct reference radiographs of any issue remain validand may be used to this standard.1.4 The plates produced to serve for use in this standardwere purposely cast to exhibit the desired discontinuity.Theplates were cast using different processes as shown in Table 1and Table 2.Hot isostatic pressing was not used on any of theplates.1.5 From time to time,there may be minor changes to theprocess for manufacturing of the reference radiograph adjunctmaterials.These changes could include changes in the films orprocessing chemicals used,changes in the dies or printing forthe cardboard mats,etc.;however,in all cases,these changesare reviewed by the Illustration Monitoring Subcommittee andall reference radiographs are reviewed against a fixed prototypeimage to ensure that there are no changes to the acceptancelevel represented by the reference radiographs.Therefore,theadjunct reference radiographs remain valid for use with thisstandard regardless of the date of production or the revisionlevel of the text standard.1.6 The values stated in inch-pound units are to be regardedas the standard.The values given in parentheses are mathemati-cal conversions to SI units that are provided for informationonly and are not considered standard.1.7 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:2E94 Guide for Radiographic ExaminationE1316 Terminology for Nondestructive ExaminationsE2669 Digital Reference Images for Titanium Castings2.2 ASTM Adjuncts:Reference Radiographs for the Inspection of TitaniumCastingsVolume I,applicable up to 1 in.(25.4 mm)3,41This 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 Sept.1,2015.Published September 2015.Originallyapproved in 1990.Last previous edition approved in 2014 as E1320-14.DOI:10.1520/E1320-15.2For 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 ASTM International Headquarters.Order Reference Radio-graph No.RRE132001.4Volumes I and II are available from ASTM International Headquarters as a set.Order Reference Radiographs RRE1320CS.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Volume II,applicable over 1 in.to 2 in.(25.4 mm to 50.8mm)4,53.Terminology3.1 DefinitionsFor definitions of terms used in thisstandard,see Terminology E1316.4.Significance and Use4.1 These
