1.1 这些试验方法包括两个程序，用于通过渗透法测量润滑脂小样本的稠度 1. / 4. -刻度锥或a 1. / 2. -锥形鳞片。这些试验方法包括测量未加工和加工穿透的程序。 1.2 未加工贯穿件通常不能像加工贯穿件那样有效地表示使用中润滑脂的稠度。后者通常优先用于检查润滑脂。 1.3 以国际单位制为单位的数值将被视为标准。括号中给出的值仅供参考。 在美国，以英寸表示的设备尺寸应视为标准。 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 这些试验方法适用于国家润滑脂研究所（NLGI）稠度值为0至4的润滑脂，仅适用于样品尺寸不允许使用试验方法的情况 D217 . 5.2 未使用或报告实际缩比贯入值。将其转换为全尺寸贯入值（参见第节 9 和 10 ). 本试验方法不旨在取代试验方法中所述的全尺寸渗透 D217 . 全尺寸贯入法的精度更好。 5.3 将加工渗透结果转换为满标度值后，可用于确定润滑脂在上述NLGI稠度值范围内的稠度。从这些试验方法中获得的结果广泛用于规范目的，但尚未确定与现场性能的相关性。 5.4 未加工的缩尺渗透结果提供了一种评估储存条件对润滑脂稠度影响的方法。

1.1 These test methods cover two procedures for measuring the consistency of small samples of lubricating greases by penetration of a 1 / 4 -scale cone or a 1 / 2 -scale cone. These test methods include procedures for the measurement of unworked and worked penetrations. 1.2 Unworked penetrations do not generally represent the consistency of greases in use as effectively as do worked penetrations. The latter are usually preferred for inspecting lubricating greases. 1.3 The values in SI units are to be regarded as the standard. The values given in parentheses are for information only. In the United States, the equipment dimensions stated in inches are to be regarded as the standard. 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 These test methods are applicable to greases of National Lubricating Grease Institute (NLGI) consistency numbers 0 to 4 and are intended for use only where the size of the sample prevents the use of Test Methods D217 . 5.2 Actual reduced-scale penetration values are not used or reported. They are converted to full-scale penetration values (see Sections 9 and 10 ). This test method is not intended to replace the full-scale penetration as described in Test Methods D217 . Precision is better in the full-scale penetration method. 5.3 Worked penetration results, after conversion to full-scale values, may be used to establish the consistency of lubricating greases within the above NLGI consistency numbers. The results obtained from these test methods are widely used for specification purposes, however, no correlation with field performance has been established. 5.4 Unworked reduced-scale penetration results provide a means of evaluating the effect of storage conditions on grease consistency.
