1.1 本规程描述了通过测试或评估由增材制造（AM）生产的试样来报告结果的标准程序。本规程提供了AM样本数据的通用格式，用于两个目的: (1) 制定进一步的数据报告要求，以及 (2) 为材料属性数据库的设计提供信息。 1.2 所有添加剂制造相关标准都需要以国际单位制表示的数值。然而，当本标准与以英寸为单位规定的任何试验方法或设备结合使用时- 磅单位报告结果时，应在括号内立即将结果转换为国际单位制。转换仅供参考，不视为标准。 1.3 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。 1.4 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====== 4.1 由于每个AM过程和设备都有其独特的变量，因此必须对用于报告用于测试或评估的样本的制备、处理和后处理的描述进行标准化。本规程旨在一致地记录与正在进行测试或评估的样本相关的材料和加工历史。文档的详细程度将与应用程序相匹配。 4.2 本规程规定了材料和工艺数据报告的最低数据元要求，目的是: 4.2.1 标准化试样描述和试验报告， 4.2.2 通过标准化AM材料数据库协助设计师， 4.2.3 通过测试和评估帮助材料可追溯性， 4.2.4 捕捉AM样本的特性-参数-性能关系，以实现预测建模和其他计算方法。

1.1 This practice describes a standard procedure for reporting results by testing or evaluation of specimens produced by additive manufacturing (AM). This practice provides a common 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 following 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 ====== 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 processing 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 requirements for reporting of material 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 relationships of AM specimens to enable predictive modeling and other computational approaches.
