1.1 本文件涵盖了评估机械性能的补充指南，包括通过添加制造（AM）制造的金属的静态/准静态和动态测试，以指导报告竣工样品或从该技术制造的印刷零件上切除的样品或两者的测试结果。 1.2 本文件旨在利用现有标准。为额外制造的金属试样以及从零件上切除的试样的机械性能测量和报告提供了指南。 1.3 本文件扩展了ISO/ASTM 52900的术语和ISO/ASTM52921的原则，并将其具体扩展到金属添加剂制造。本文件的应用主要是为了在无法从可用的测试方法中获得AM有意义的方向/方向的情况下，提供方向指定的指导。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 尽管许多附加制造材料的机械性能评估可以使用现有测试标准中为常规材料制定的指南进行，但常规材料测试的坐标系和术语（例如，ASTM 电子399 ，ASTM公司 电子647 ISO 12108和ISO 12135）不足以适用于由金属AM生产的样品/零件的全光谱，而不会造成混淆。本文件基于ISO/ASTM 52921的术语和原则，并将其扩展到金属AM。本文件的应用主要是为了在无法从可用测试方法中获得AM有意义的方向/方向的情况下，提供方向指定的指导。 5.2 应理解，本文件中的解释和指南不会改变试验方法的有效性要求，也不能使用本文件将“无效”数据（即根据试验方法）的名称更改为“有效”条件。 本文件主要涉及不可能或不实际获得基于定向/方向指定的有意义数据的情况，这些数据目前包含在为常规加工材料制定的标准中。

1.1 This document covers supplementary guidelines for evaluation of mechanical properties including static/quasi-static and dynamic testing of metals made by additive manufacturing (AM) to provide guidance toward reporting results from testing of as-build specimen or those excised from printed parts made by this technique or both. 1.2 This document is provided to leverage already existing standards. Guidelines are provided for mechanical properties measurements and reporting for additively manufactured metallic specimen as well as those excised from parts. 1.3 This document expands upon the nomenclature of ISO/ASTM 52900 and principles of ISO/ASTM 52921 and extends them specifically to metal additive manufacturing. The application of this document is primarily intended to provide guidance on orientation designations in cases where meaningful orientation/direction for AM cannot be obtained from available test methods. 1.4 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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. ====== Significance And Use ====== 5.1 Although evaluation of mechanical properties of many additively manufactured materials can be conducted using the guidelines developed for conventional materials within existing testing standards, the coordinate systems and nomenclature specific to conventional materials testing (for example, in ASTM E399 , ASTM E647 , ISO 12108, and ISO 12135) are not sufficient to be applicable across the full spectrum of specimen/parts produced by metal AM without causing confusion. This document is based on the nomenclature and principles of ISO/ASTM 52921 and extends them specifically to metal AM. The application of this document is primarily intended to provide guidance on orientation designations in cases in which meaningful orientation/direction for AM cannot be obtained from available test methods. 5.2 It shall be understood that the interpretations and guidelines in this document do not alter the validity requirements of test methods nor can this document be used to change the designation of “invalid” data (that is according to test methods) to a “valid” condition. This document is primarily concerned with cases in which it is not possible or practical to obtain meaningful data based on orientation/direction designations that are currently covered in standards developed for conventionally processed materials.
