1.1 本试验方法涵盖了在1200 r/min和13.8 MPa下运行的定容叶片泵试验程序。 1.2 以SI单位表示的值将被视为标准值。本标准不包括其他计量单位。 1.2.1 例外- 本试验方法中设备中使用的英寸紧固件和英寸O形圈没有SI等效物。 1.2.2 例外- 在某些情况下，作为安全措施，英文压力值在括号中给出。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.4 本国际标准是根据《关于制定国际标准、指南和标准的原则的决定》中确立的国际公认的标准化原则制定的世界贸易组织技术性贸易壁垒委员会发布的建议。 ======意义和用途====== 5.1 本试验方法是在定容叶片泵中运行的非石油和石油液压油磨损特性的指标。叶片泵的过度磨损可能会导致关键应用中液压系统的故障。

1.1 This test method covers a constant volume vane pump test procedure operated at 1200 r/min and 13.8 MPa. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 Exception— There are no SI equivalents for the inch fasteners and inch O-rings that are used in the apparatus in this test method. 1.2.2 Exception— In some cases English pressure values are given in parentheses as a safety measure. 1.3 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. 1.4 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 This test method is an indicator of the wear characteristics of non-petroleum and petroleum hydraulic fluids operating in a constant volume vane pump. Excessive wear in vane pumps could lead to malfunction of hydraulic systems in critical applications.
