本标准采用ISO/ASTM 52921:2013，该标准规定了与添加剂制造（AM）技术的坐标系和测试方法相关的术语、术语定义、术语描述、术语和首字母缩略词，以使AM用户、生产者、研究人员、教育工作者、媒体和其他人使用的术语标准化，尤其是在报告AM系统部件测试结果时。术语包括机器/系统及其坐标系的定义，以及零件的位置和方向。在可能的情况下，其目的是符合ISO 841，并阐明这些原则对添加剂制造的具体适应性。

This Standard adopts ISO/ASTM 52921:2013, which specifies the terms, definitions of terms, descriptions of terms, nomenclature, and acronyms associated with coordinate systems and testing methodologies for additive manufacturing (AM) technologies in an effort to standardize terminology used by AM users, producers, researchers, educators, press/media, and others, particularly when reporting results from testing of parts made on AM systems. Terms included cover definitions for machines/systems and their coordinate systems plus the location and orientation of parts. It is intended, where possible, to be compliant with ISO 841 and to clarify the specific adaptation of those principles to additive manufacturing.
