Designation:E244305(Reapproved 2018)1Standard Guide forVerifying Computer-Generated Test Results Through TheUse Of Standard Data Sets1This standard is issued under the fixed designation E2443;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.1NOTESections 3.1.2,3.1.4,4.2,4.7.3,4.8.4,and 4.10 were editorially corrected in August 2018.1.Scope1.1 This guide establishes a process for the verification ofapplication software used to calculate the mechanical proper-ties of materials.1.2 This guide has two purposes:(1)it provides guidelinesfor creating standard data sets for verifying computer-generated test results,and(2)it describes how users can verifywhether the calculations in their application software produceaccurate,acceptable results.This does not ensure that thesoftware will produce correct results in all cases.The verifi-cation is only for those conditions covered by the standard datasets.This guide uses the concept of standard“data sets,”whichare made available by the ASTM groups responsible for eachof the individual standards.1.3 This guide defines the terminology,the format,and theprocess for the use of these data sets and how the data sets areto be used for verification.It does not define the specific datasets required to verify each of the application standards.Rather,such data sets would become a necessary part of thestandard and would be classified as an adjunct in accord withthe definition in section B29 of the“Form and Style for ASTMStandards.”This classifies an adjunct as any material that isrequired for use of the standard but is not practicable to publishas an integral part of the standard.1.4 In Annex A1 there is an example of how such data setswould be made available for one example standard.1.5 Because the verification data sets are contained in filessupplied to the application software in the computer,thisprocedure only provides verification of post-test calculationsperformed by the computer system.It does not evaluate thedata acquisition system,real-time calculations,or any otherpart of the software beyond the post-test calculations.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2E1942 Guide for Evaluating Data Acquisition Systems Usedin Cyclic Fatigue and Fracture Mechanics Testing3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 ASCIIAmerican National Standard Code for Infor-mation Interchange.Data supplied in this form is readable byany computer system and will be displayed on the screen inhuman readable form.3.1.2 raw dataThe sampled values of a sensor output.3.1.3 data setA self-contained set of data consisting of apreamble,specimen information,and basic data.This may takethe form of a printed document or a computer data file.3.1.4 derived dataData obtained through the processingof the raw data.3.1.5 expected resultsThe results accompanying the datasets that are expected from the computer.3.1.6 item separatorA special character(delimiter)usedto separate items that appear on one line of ASCII characters.3.1.7 keywordA text word or combination of charactersthat uniquely identify an item of information in the SpecimenInformation section.Such keywords are defined in a preambleto the data set within the standard in which they are to be used.3.1.8 line terminatorAcharacter or sequence of charactersused to signify the end of a line of ASCII characters.1This guide is under the jurisdiction of ASTM Committee E08 on Fatigue andFracture and is the direct responsibility of Subcommittee E08.03 on AdvancedApparatus and Techniques.Current edition approved June 1,2018.Published August 2018.Originallyapproved in 2005.Last previous edition approved in 2010 as E2443-05.DOI:10.1520/E2443-05R18E01.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.1.9 preambleA text section describing the data set,which standard it applies to,any critical i
