1.1 本标准作为现有标准或现有标准变体的指南，这些标准或变体可能适用于确定使用添加剂制造工艺制造的材料的特定机械性能。 1.2 如许多参考标准所述，有几个因素可能会影响报告的性能，包括材料、材料各向异性、材料制备方法、孔隙度、试样制备方法、测试环境、试样对齐和夹持、测试速度和测试温度。应根据实践记录已知的这些因素 F2971 以及参考标准的指南。 1.3 以下标准未在指南中直接提及，但也包含在通过添加剂制造制成的金属试样的测试中可能有用的信息: A370型 , A1058号 , B211 , B348型 , B557 , B565 , B724 , B769 , E3 , E6 , E7 , E290型 , E467 , E468 , E837 , E915 , E1049号 , E1823 , E1942 . 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 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。

1.1 This standard serves as a guide to existing standards or variations of existing standards that may be applicable to determine specific mechanical properties of materials made with an additive manufacturing process. 1.2 As noted in many of these referenced standards, there are several factors that may influence the reported properties, including material, material anisotropy, method of material preparation, porosity, method of specimen preparation, testing environment, specimen alignment and gripping, testing speed, and testing temperature. These factors should be recorded, to the extent that they are known, according to Practice F2971 and the guidelines of the referenced standards. 1.3 The following standards are not referred to directly in the guide but also have information that may be useful in the testing of metal test specimens made via additive manufacturing: A370 , A1058 , B211 , B348 , B557 , B565 , B724 , B769 , E3 , E6 , E7 , E290 , E467 , E468 , E837 , E915 , E1049 , E1823 , E1942 . 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 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.
