1.1 本文件规定了测量非工业场所常用的材料挤压型AM机器运行过程中排放的有害物质的测试方法，并包括减少这些有害物质的非规范性建议。 1.2 本文件规定了当前常用材料在运行过程中此类机器排放的一些主要危险物质，描述了测量危险物质的附加信息和相关测试方法，并包括减少危险物质的注意事项和基本对策。 1.3 本文件规定了如何测量非- 安装此类机器的工业场所（学校、公共场所等），并通过管理现场设施、机器、细丝和添加剂制造的产品来保持可接受的工作环境，以减少危险物质。 1.4 然而，本文件并不涵盖所有气相化学排放。仅包括从正己烷到正十六烷的一系列挥发性有机化合物（VOC），包括醛类。附件A和B给出了减少化学排放和改善工作环境的考虑因素。 1.5 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 a test method for measuring hazardous substances emitted during the operation of material extrusion type AM machines commonly used in the non-industrial places and includes non-normative suggestions for ways to reduce them. 1.2 This document specifies some of the main hazardous substances emitted from this type of machine during operation for currently commonly used materials, it describes the additional information and the associated test method for measuring hazardous substances, and includes considerations for reducing the hazardous substances and basic countermeasures. 1.3 This document specifies how to measure concentrations of hazardous substances generated in the non- industrial places (school, public place and so on) in which this type of machines are installed, and to maintain an acceptable work environment by managing field facilities, machines, filaments, and additive manufactured products for the reduction of hazardous substances. 1.4 However, this document does not cover all gas-phase chemical emissions. Only a range of Volatile Organic Compounds (VOCs) from n-hexane to n-hexadecane, including aldehydes are included. Considerations for reducing chemical emissions and for improving the work environment are given in Annexes A and B. 1.5 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.
