本SAE推荐规程由SAE和“工业润滑脂的标准分类和规范”一节与ASTM和NLGI合作制定。其目的是协助重型车辆部件的设计，以及重型车辆（如卡车和公共汽车）上某些部件润滑脂的选择和销售。本文包含的信息将有助于理解与重型车辆润滑脂的性能、名称和服务应用相关的术语。

This SAE Recommended Practice was developed by SAE, and the section "Standard Classification and Specification for Service Greases" cooperatively with ASTM, and NLGI. It is intended to assist those concerned with the design of heavy duty vehicle components, and with the selection and marketing of greases for the lubrication of certain of those components on heavy duty vehicles like trucks and buses. The information contained herein will be helpful in understanding the terms related to properties, designations, and service applications of heavy duty vehicle greases.
