1.1 本文件规定了电子束粉末床金属熔化（PBF-EB/M）的特点，并提供了详细的设计建议。 1.2 一些基本原则也适用于其他增材制造（AM）工艺，前提是适当考虑工艺特定特征。 1.3 本文件还通过汇集有关该工艺的相关知识并扩展ISO/ASTM 52910的范围，提供了与粉末床融合（PBF）使用相关的设计指南的最新审查 ( 1. ) . 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。

1.1 This document specifies the features of electron beam powder bed fusion of metals (PBF-EB/M) and provides detailed design recommendations. 1.2 Some of the fundamental principles are also applicable to other additive manufacturing (AM) processes, provided that due consideration is given to process-specific features. 1.3 This document also provides a state of the art review of design guidelines associated with the use of powder bed fusion (PBF) by bringing together relevant knowledge about this process and by extending the scope of ISO/ASTM 52910 ( 1 ) . 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.
