1.1 本文件规定了增材制造（AM）技术领域内AM操作员在金属零件生产方面的活动和责任。 1.2 本文件旨在为一般工业应用中AM机器操作员的资格认证提供指导。如果AM操作员的资格有行业特定要求，如航空航天应用的ISO/ASTM 52942，则使用这些行业特定标准代替本文件。 1.3 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 specifies the activities and responsibilities of the AM operators in the field of the additive manufacturing (AM) technologies dealing with metallic parts production. 1.2 This document is intended to provide guidance 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. 1.3 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.
