1.1 本文件确定了AM操作员在涉及金属零件生产的增材制造技术领域的资格认证所需的能力和责任，特别是在使用粉末床熔化-金属激光束（PBF-LB/M）方面。 1.2 本文件确定了PBF-LB/M机器操作人员的理论和实践评估标准。PBF-LB/M操作员预计要执行的活动和程序也是本文件的一部分。 1.3 本文件旨在提供一般工业应用中AM机器操作员资格的大纲。如果存在AM操作员资格的行业特定要求，如航空航天应用的ISO/ASTM 52942，则这些行业- 使用特定标准代替本文件。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This document identifies the capabilities and responsibilities required for the qualification of the AM operators on the field of the additive manufacturing technologies dealing with metallic parts production, specifically for the employment of powder bed fusion – laser beam with metals (PBF-LB/M). 1.2 This document identifies criteria for the theoretical and practical assessment of personnel operating PBF-LB/M machines. The activities and procedures foreseen to be performed by the PBF-LB/M operator are also part of this document. 1.3 This document is intended to provide an outline for qualification of AM machine operators in general industrial applications. Where industry-specific requirements exist for the qualification of AM operators, such as ISO/ASTM 52942 for aerospace applications, those industry-specific standards are used instead of this document. 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.
