1. Scope
1.1 This practice describes a standard procedure for report- ing results by testing or evaluation of specimens produced by additive manufacturing (AM). This practice provides a com- mon format for presenting data for AM specimens, for two purposes: (1) to establish further data reporting requirements, and (2) to provide information for the design of material property databases. 1.2 The values stated in SI units are required for all additive manufacturing related standards. However, when this standard is used in combination with any test method or equipment specified in inch-pound units the results should be reported with mathematical conversions to SI units immediately follow- ing in parentheses. The conversions shall be provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.4 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
4. Significance and Use
4.1 Due to variables unique to each AM process and piece of equipment, it is critical to standardize descriptions used to report the preparation, processing, and post processing of specimens produced for tests or evaluation. The intent of this practice is to consistently document the materials and process- ing history associated with specimens undergoing test or evaluation. The level of detail for the documentation will match the application. 4.2 This practice establishes minimum data element require- ments for reporting ofmaterial and process data for the purpose of: 4.2.1 Standardizing test specimen descriptions and test reports, 4.2.2 Assisting designers by standardizing AM materials databases, 4.2.3 Aiding material traceability through testing and evaluation, 4.2.4 Capturing property-parameter-performance relation- ships of AM specimens to enable predictive modeling and other computational approaches.
5. Requirements
5.1 This section specifies the data and information required to be reported for test specimens built using AM. 5.1.1 Materials and Process Reporting Requirements—The following 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 materials required for AM operations. (2) Procedure for using or re-using feedstock material. 5.1.1.2 A description of all non-standard processes used or deviations, or both, from process standards used. 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 from feedstock material. (2) Placement and orientation of the test specimen in the build chamber. 5.1.1.4 A description of all non-standard processes used or deviations, or both, from process standards used. 5.1.2 Test and Inspection Reporting Requirements—The following test and inspection information must be reported for test 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, with tolerances specified. (2) The test plan. Note: this can be incorporated in the materials and process specifications. (3) Test procedures. (4) Non-destructive inspection procedures and results. 5.1.2.2 A description of all non-standard test methods used or deviations, or both, from standard test methods used. 5.1.2.3 Post Processing Reporting Requirements—If post processing was performed on the test specimens and is not included in 5.1.1 or 5.1.2, then it must be reported. Post processing may include, but is not limited to support removal, stress relief, part consolidation, heat treatment, and surface finishing.
