1.1 本指南涵盖了现有标准或现有标准的变体，这些标准可用于确定采用材料挤出（MEX）增材制造（AM）工艺制造的聚合物试样的特定静态机械性能。本文件中涵盖的测试方法是根据以往材料鉴定程序提供的经验提供的建议。在评估特定应用的材料性能时，也可以考虑其他测试方法。 包括测试和表征前的材料处理建议，因为它们会极大地影响材料性能。最终用户应确定推荐的测试是否充分评估了预期应用的材料性能。 1.2 单位- 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 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。 ====意义和用途====== 4.1 如第节中的许多标准所述 2. ，有多种因素可能会影响所报告的性能，包括材料选择、材料各向异性、材料储存和制备方法、孔隙率、样品储存和制准备方法、制造过程中的定向和样品构建板位置、测试环境、测试过程中的样品对准和夹持、测试速度和测试温度。 应根据实践记录这些因素 1971年2月 以及参考标准的指导方针。本指南旨在向用户介绍使用材料挤出（MEX）制造的添加剂制造聚合物试样的静态机械测试的最佳实践。

1.1 This guide covers existing standards or variations of existing standards that may be applicable to determine specific static mechanical properties of polymeric specimens fabricated with the material extrusion (MEX) additive manufacturing (AM) process. The test methods covered within this document are recommendations supplied coming from the experience previous material qualification programs have provided. Additional test methods may be considered as well depending when evaluating material performance for specific applications. Recommendations for material handling prior to testing and characterization are included as they can greatly affect material properties. It is for the end user to determine if the recommended tests adequately evaluate the material performance for the intended application. 1.2 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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. ====== Significance And Use ====== 4.1 As noted in many of the standards in Section 2 , there are multiple factors that may influence the reported properties, including material choice, material anisotropy, methods of material storage and preparation, porosity, methods of specimen storage and preparation, orientation and specimen build plate location during fabrication, testing environment, specimen alignment and gripping during testing, testing speed, and testing temperature. These factors should be recorded according to Practice F2971 and the guidelines of the referenced standards. This guide is intended to inform users of best practices for static mechanical testing of additive manufactured polymer specimens fabricated using material extrusion (MEX).
