1.1 本指南旨在向读者介绍用金属粉末床熔融增材制造工艺制造的表面纹理测量和表征技术。它向读者介绍了可能适用于表面纹理测量和表征的现有标准。 1.2 单位- 以国际单位制表示的数值应视为标准。本标准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====== 3.1 有必要确定表面纹理测量和表征的最佳策略，以提高对表面评估的信心，以及对制造表面、制造工艺和所需功能之间寻求的任何进一步比较和相关性的信心。此外，表面纹理的测量和表征在摩擦学领域以及零件质量的确定和规范中具有重要意义。本指南旨在为工业界和学术界的测量技术用户提供优化金属粉末床聚变（PBF）制造工艺产生的表面测量的良好实践。虽然本指南的重点是金属PBF生产的表面，但一些参考方法也适用于其他制造工艺生产的表面。

1.1 This guide is designed to introduce the reader to techniques for surface texture measurement and characterization of surfaces made with metal powder bed fusion additive manufacturing processes. It refers the reader to existing standards that may be applicable for the measurement and characterization of surface texture. 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 ====== 3.1 Determining optimal strategies for the measurement and characterization of surface texture is necessary to increase confidence in the assessment of surfaces and in any further comparisons and correlations sought between manufactured surfaces, manufacturing processes, and desired functionality. Further, measurement and characterization of surface texture have implications in the field of tribology and in the determination and specification of part quality. This guide is designed to provide users of measurement technologies in both industry and academia with good practice for optimizing measurements of surfaces produced by metal powder bed fusion (PBF) manufacturing processes. While the focus of this guide is on surfaces produced by metal PBF, some of the referenced methods may also be appropriate for surfaces produced by other manufacturing processes.
