1、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 indica
2、tes 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 reproduction
3、s 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 adjunc
4、t 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
5、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 Ref
6、erence 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
7、 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 adj
8、unct 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 w

10、r,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
