1.1 本文件规定了热塑性材料试样通过激光粉末床熔化（PBF-LB/P）（通常称为激光烧结）制备时应遵循的一般原则。（PBF-LB/P）工艺用于逐层制备试样，其中热能选择性地熔化粉末床的区域。本文件为建立可重复和可报告的烧结条件提供了基础。其目的是促进描述主要工艺参数的一致性，建立烧结过程的方向，并建立报告烧结条件的统一做法。 1.2 本文件未规定测试程序本身。 1.3 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 general principles to be followed when test specimens of thermoplastic materials are prepared by laser-based powder bed fusion (PBF-LB/P), which is commonly known as laser sintering. The (PBF-LB/P) process is used to prepare test specimens layer upon layer in which thermal energy selectively fuses regions of a powder bed. This document provides a basis for establishing reproducible and reportable sintering conditions. Its purpose is to promote uniformity in describing the main process parameters, build orientation of the sintering process and also to establish uniform practice in reporting sintering conditions. 1.2 This document does not specify the test procedure itself. 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.
