ASTM F2971-13(2021)

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Designation: F2971 − 13 (Reapproved 2021)
Standard Practice for
Reporting Data for Test Specimens Prepared by Additive
Manufacturing
This standard is issued under the fixed designation F2971; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
