1.1 本试验方法涵盖在1200℃下运行的定容叶片泵试验程序 r/min和13.8 兆帕。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.2.1 例外情况- 在本试验方法中，仪器中使用的英制紧固件和英制O形圈没有SI等效物。 1.2.2 例外情况- 在某些情况下，括号中给出了英制压力值，作为安全措施。 1.3 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. 4. 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 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的磨损特性的指示器。叶片泵过度磨损可能导致关键应用中的液压系统故障。

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.
