1.1 本试验方法涵盖了检测和估计润滑脂中有害颗粒的程序。 1.2 本试验方法适用于所有润滑脂。它也可用于测试其他半固态或粘性材料。润滑脂填充物，如石墨和二硫化钼，可以通过首先将其混合到已知不含有害颗粒的矿脂或润滑脂中来测试是否存在研磨性污染物。 1.3 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。 每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。在文本中，国际单位显示在括号中。 1.4 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。 1.5 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 就与现场性能的相关性而言，划痕数量的重要性尚未确定。对塑料具有研磨性的颗粒不一定对钢或其他轴承材料具有研磨性。 在样品3中使用的污染物中获得了一些相关性（参见 10.1.1 )在实验室滚珠轴承磨料磨损试验中的磨损率大于样品2中的污染物。 注1: 获得的划痕数量不能用于绘制润滑脂之间的细微差异，而是将其分为两个或三个一般类别。其中一种可能的划分是: 1. . 少于10处划痕 2. . 10到40处划痕 3. . 40多处划痕 5.2 这种测试方法的一个优点是，每个测试只需几分钟即可运行。 5.3 本试验方法用于质量控制和规范目的。

1.1 This test method covers a procedure for the detection and estimation of deleterious particles in lubricating grease. 1.2 This test method is applicable to all lubricating greases. It can also be used to test other semi-solid or viscous materials. Grease fillers, such as graphite and molybdenum disulfide, can be tested for abrasive contaminants by first mixing them into petrolatum or grease known to be free of deleterious particles. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Within the text, the SI units are shown in brackets. 1.4 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. 1.5 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. ====== Significance And Use ====== 5.1 The significance of the number of scratches as far as correlation with field performance is concerned has not been established. A particle which is abrasive to plastic will not necessarily be abrasive to steel or other bearing materials. Some correlation was obtained in that the contaminant used in Sample 3 (see 10.1.1 ) had a greater wear rate in a laboratory ball bearing abrasive wear test than the contaminant in Sample 2. Note 1: The number of scratches obtained cannot be used to draw fine differences between greases, but rather, to group them into two or three general classes. One such possible division could be: 1. . less than 10 scratches 2. . 10 to 40 scratches 3. . more than 40 scratches 5.2 An advantage of this test method is that each test takes only a few minutes to run. 5.3 This test method is used for quality control and specification purpose.
