1.1 本试验方法描述了一种通过激光诱导击穿光谱（LIBS）定量测定在用润滑剂中发现的磨屑的方法。LIBS是一种分析技术，使用短激光脉冲对材料进行微热等离子体烧蚀，然后使用光谱工具进行分析。 2. 1.2 该方法涵盖了合金分类和磨屑尺寸的方法。磨损碎屑源包括但不限于: (1) 芯片收集器和芯片检测器设备， (2) 过滤器， (3) 铁谱图，以及 (4) 松散颗粒。仪器默认材料库中包含的23种测试合金和金属列于 表1 . 1.3 合金分类和磨屑尺寸的方法不限于 表1 . 该仪器能够根据需要包括额外的合金和金属。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户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。 1.6 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 在许多情况下，设备故障模式是通过磨损碎屑识别的，这些磨损碎屑不是在使用过的润滑油样本中捕获的，而是通过芯片探测器、过滤器或其他方式捕获的。该技术的用户包括但不限于原始设备制造商（OEM）、商业航空公司、民用航空运营商、维修和大修（MRO）设施以及军事维修人员。

1.1 This test method describes a means for quantitative determination of wear debris found in in-service lubricants by laser-induced breakdown spectroscopy (LIBS). LIBS is an analytical technology that uses short laser pulses to create micro hot-plasma ablation of a material and then employs spectroscopic tools for analysis. 2 1.2 This method covers the means for alloy classification and sizing of wear debris. Wear debris sources can include, but are not limited to: (1) chip collector and chip detector devices, (2) filters, (3) ferrograms, and (4) loose particles. The 23 tested alloys and metals included in the default material library of the instrument are listed in Table 1 . 1.3 The method for alloy classification and sizing of wear debris is not limited to the list of alloys in Table 1 . The instrument has the capability of including additional alloys and metals as required. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 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 ====== 5.1 In many cases, equipment failure modes are identified by wear debris that is not captured in used lubricating oil samples but captured on chip detectors, filters or by other means. Users of this technique include, but are not limited to, original equipment manufacturers (OEMs), commercial airlines, civil aerospace operators, maintenance repair and overhaul (MRO) facilities, and military maintenance personnel.
