1、Designation:E15515Standard Reference Radiographs forInspection of Aluminum and Magnesium Castings1This standard is issued under the fixed designation E155;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A nu
2、mber in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.These Reference Radiographs have been developed in cooperation with the Quality Control Committee and Aerospace Research andTesting Committee of the Aer
3、ospace Industries Association.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 These reference radiographs illustrate the types anddegrees of discontinuities that may be found in aluminum-alloyand magnesium-alloy castings.The castings illustrated are in
4、thicknesses of14in.(6.35 mm)and34in.(19.1 mm).Thereference radiograph films are an adjunct to this document andmust be purchased separately from ASTM International ifneeded.1.2 These film reference radiographs are not intended toillustrate the types and degrees of discontinuities found inaluminum-al
5、loy and magnesium-alloy castings when perform-ing digital radiography.If performing digital radiography ofaluminum-alloy castings,refer to Digital Reference ImageStandard E2422.If performing digital radiography ofmagnesium-alloy castings,refer to Digital Reference ImageStandard E2869.1.3 This docume
6、nt may be used where no other applicabledocument exists,for other material thicknesses for which it hasbeen found to be applicable and for which agreement has beenreached between the purchaser and the manufacturer.1.4 From time to time,there may be minor changes to theprocess for manufacturing of th
7、e 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
8、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
9、.1.5 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.1.6 This standard does not purport to address all of thesafety concerns,if any,
10、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.NOTE1Vol I:The set of reference radiographs consists of 13 platescovering discontinuities in alum
11、inum-alloy castings and 10 plates cover-ing discontinuities in magnesium-alloy castings.Each plate is held in an812by 11-in.(216 by 279-mm)cardboard frame and each plate illustrateseight grades of severity for the discontinuity in approximately a 2 by 2-in.(51 by 51-mm)area.The cardboard frames are
12、contained in a 1012by1112-in.(267 by 292-mm)ring binder.The reference radiographs are notimpacted by this revision.There have been no revisions to the adjunctreference radiographs since original issue.The adjunct reference radio-graphs of any issue remain valid and may be used to this standard.Vol.I
13、I:The set of reference radiographs consists of four plates coveringdiscontinuities in magnesium-alloy castings only.Each plate is held in an812by 11-in.(216 by 279-mm)cardboard frame and illustrates eightgrades of severity for the discontinuity(with the exception of discretediscontinuities,where onl
14、y one example of each discontinuity is given).NOTE2Reference radiographs applicable to aluminum and magne-sium die castings up to 1 in.(25 mm)in thickness are contained inReference Radiographs E505.2.Referenced Documents2.1 ASTM Standards:2E94 Guide for Radiographic ExaminationE505 Reference Radiogr
