Designation:F297113Standard Practice forReporting Data for Test Specimens Prepared by AdditiveManufacturing1This standard is issued under the fixed designation F2971;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 describes a standard procedure for report-ing results by testing or evaluation of specimens produced byadditive manufacturing(AM).This practice provides a com-mon format for presenting data for AM specimens,for twopurposes:(1)to establish further data reporting requirements,and(2)to provide information for the design of materialproperty databases.1.2 The values stated in SI units are required for all additivemanufacturing related standards.However,when this standardis used in combination with any test method or equipmentspecified in inch-pound units the results should be reportedwith mathematical conversions to SI units immediately follow-ing in parentheses.The conversions shall be provided forinformation only and are not considered standard.1.3 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:2D638 Test Method for Tensile Properties of PlasticsE8M Test Methods for Tension Testing of Metallic MaterialsMetric(Withdrawn 2008)3F2792 TerminologyforAdditiveManufacturingTechnologies,F2921 TerminologyforAdditiveManufacturingCoordinate Systems and Test MethodologiesF2924 Specification for Additive Manufacturing Titanium-6Aluminum-4 Vanadium with Powder Bed Fusion3.Terminology3.1 Definitionsshall be in accordance with TerminologiesF2792 and F2921.4.Significance and Use4.1 Due to variables unique to each AM process and pieceof equipment,it is critical to standardize descriptions used toreport the preparation,processing,and post processing ofspecimens produced for tests or evaluation.The intent of thispractice is to consistently document the materials and process-ing history associated with specimens undergoing test orevaluation.The level of detail for the documentation willmatch the application.4.2 This practice establishes minimum data element require-ments for reporting of material and process data for the purposeof:4.2.1 Standardizing test specimen descriptions and testreports,4.2.2 Assisting designers by standardizing AM materialsdatabases,4.2.3 Aiding material traceability through testing andevaluation,4.2.4 Capturing property-parameter-performance relation-ships of AM specimens to enable predictive modeling andother computational approaches.5.Requirements5.1 This section specifies the data and information requiredto be reported for test specimens built using AM.5.1.1 Materials and Process Reporting RequirementsThefollowing materials and processes information must be re-ported for test specimens built using AM:5.1.1.1 All standard material specifications used.Informa-tion from these specifications should include,as minimum:(1)Description and preparation of feedstock materialsrequired for AM operations.(2)Procedure for using or re-using feedstock material.5.1.1.2 A description of all non-standard processes used ordeviations,or both,from process standards used.1This practice is under the jurisdiction of ASTM Committee F42 on AdditiveManufacturing Technologies and is the direct responsibility of SubcommitteeF42.01 on Test Methods.Current edition approved Dec.15,2013.Published March 2014.DOI:10.1520/F2971-132For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.1.1.3 All standard process specifications used.Informa-tion form these specifications should include,as a minimum:(1)All processes used to produce the specimen fromfeedstock material.(2)Placement and orientation of the test specimen in thebuild chamber.5.1.1.4 A description of all non-standard processes used ordeviations,or both,from process standards used.5.1.2 Test and Inspection Reporting RequirementsThefollowing test and inspection information must be reported fortest specimens built using AM:5.1.2.1 All standard test and inspection methods used.Information from these standards test methods should include,as a minimum:(1)The shape and dimensions of the test specimens,withtolerances specified.(2)The test plan.Note:this can be incorporated in themate
