Designation:E141109Standard Practice forQualification of Radioscopic Systems1This standard is issued under the fixed designation E1411;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 practice provides test and measurement details formeasuring the performance of X-ray and Gamma ray radio-scopic systems.Radioscopic examination applications arediverse.Therefore,system configurations are also diverse andconstantly changing as the technology advances.1.2 This practice is intended as a means of initially quali-fying and re-qualifying a radioscopic system for a specifiedapplication by determining its performance level when oper-ated in a static mode.System architecture including the meansof radioscopic examination record archiving and the methodfor making the accept/reject decision are also unique systemfeatures and their effect upon system performance must beevaluated.1.3 The general principles,as stated in this practice,applybroadly to transmitted-beam penetrating radiation radioscopysystems.Other radioscopic systems,such as those employingneutronsandComptonback-scatteredX-rayimagingtechniques,are not covered as they may involve equipment andapplication details unique to such systems.1.4 UnitsThe values stated in SI units are to be regardedas standard.No other units of measurement are included in thisstandard.1.5 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.For information onsafety requirements,refer to the applicable documents listed inSection 2.2.Referenced Documents2.1 ASTM Standards:2E747 Practice for Design,Manufacture and Material Group-ing Classification of Wire Image Quality Indicators(IQI)Used for RadiologyE1025 Practice for Design,Manufacture,and MaterialGrouping Classification of Hole-Type Image Quality In-dicators(IQI)Used for RadiologyE1255 Practice for RadioscopyE1316 Terminology for Nondestructive ExaminationsE1647 Practice for Determining Contrast Sensitivity in Ra-diologyE2002 Practice for Determining Total Image Unsharpness inRadiology2.2 Other Standard:3EN 4622 Step Hole IQIEN 4625 Duplex Wire IQI3.Terminology3.1 DefinitionsFor definitions of terms used in thispractice,see Terminology E1316.4.Summary of Practice4.1 This practice provides a standardized procedure for theinitial qualification and requalification of a radioscopic systemto establish radioscopic examination capabilities for a specifiedrange of applications.4.2 This practice is intended for use in association with astandardpracticegoverningtheuseofradioscopicexamination,such as Practice E1255.4.3 This practice specifies the procedures to be used indetermining the performance level of the radioscopic system.Unique system features,including component selection,sys-tem architecture,programmability and image archiving capa-bilities are important factors and are taken into account in thispractice.The overall system performance level,as well as keysystem features,are to be recorded in a qualification documentwhich shall qualify the performance level of the total radio-scopic system.An example of the Radioscopic System Quali-fication document form is included in the Appendix.Thisdocument may be tailored to suit the specific application.1This practice is under the jurisdiction of ASTM Committee E07 on Nonde-structive 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 2006 as E1411-01(2006).DOI:10.1520/E1411-09.2For 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 American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.Significance and Use5.1 As with conventional radiography,radioscopic exami-nation is broadly applicable to the many materials and objectconfigurations which may be penetrated with X-rays or gammarays.The high degree of variation in architecture and perfor-mance among radioscopic systems due to component selection,physical arrangement and object variables,makes it necessaryto establish the level of performance which the selectedradioscopic system is capable of achieving in specific applica-tions.The manufacturer of the radioscopic s
