1.1 本规程涵盖了对用于发电的蒸汽轮机和燃气轮机（作为单独或联合循环涡轮机）中使用的矿物汽轮机油进行有效监测的要求。该实践包括取样和测试计划，以验证润滑剂在其整个生命周期中的状态，并确保所需的改进，使润滑剂的当前状态处于可接受的目标范围内。本规程不适用于辅助设备润滑油的状态监测；建议参考适当的规程（参见规程 D6224 ). 1.2 本标准并不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。 1.3 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====== 4.1 此做法旨在帮助用户，特别是发电厂操作和维护部门，保持涡轮机所有部件的有效润滑，并防止出现与油降解和污染相关的问题。本实践中提到的各种测试参数的值纯粹是指示性的。事实上，为了正确解释结果，应该考虑许多因素，如设备类型、操作工作量、润滑油回路的设计和加满液位。

1.1 This practice covers the requirements for the effective monitoring of mineral turbine oils in service in steam and gas turbines, as individual or combined cycle turbines, used for power generation. This practice includes sampling and testing schedules to validate the condition of the lubricant through its life cycle and by ensuring required improvements to bring the present condition of the lubricant within the acceptable targets. This practice is not intended for condition monitoring of lubricants for auxiliary equipment; it is recommended that the appropriate practice be consulted (see Practice D6224 ). 1.2 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. 1.3 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 ====== 4.1 This practice is intended to assist the user, in particular the power-plant operations and maintenance departments, to maintain effective lubrication of all parts of the turbine and guard against the onset of problems associated with oil degradation and contamination. The values of the various test parameters mentioned in this practice are purely indicative. In fact, for proper interpretation of the results, many factors, such as type of equipment, operation workload, design of the lubricating oil circuit, and top-up level, should be taken into account.
