航空推进驱动系统的润滑剂性能源自油的物理性质和与油配方相关的化学属性。粘度、压力粘度系数和全膜牵引系数等所有特性都是润滑液的固有特性。化学特性对于在表面上形成保护性边界润滑膜以防止磨损和擦伤至关重要。为了确保性能并为工程设计提供所需信息，正在研究至少五种油性质或属性的测试方法:（1）压力粘度系数，（2）全膜牵引系数，（3）抗擦伤性，（4）耐磨性和（5）微蚀倾向。虽然粘度与温度的数据很容易获得，但必须在航空推进硬件系统的相关条件下测量上述五个特性或属性。 本文件（ARP6156）描述了胶合和耐磨性的试验方法。应注意的是，试验方法结果仅限于选定的试验条件，这可能无法代表在使用中遇到的广泛条件。

The lubricant performance capability for aero propulsion drive systems is derived from the physical properties of the oil and the chemical attributes associated with the oil formulation. All properties, such as viscosity, pressure-viscosity coefficient and full-film traction coefficient are inherent properties of the lubricating fluid. Chemical attributes are critical for the formation of protective boundary lubricating films on the surfaces to prevent wear and scuffing. To assure performance and to provide needed information for engineering design, test methodologies for at least five oil properties or attributes are being addressed: (1) pressure-viscosity coefficient, (2) full-film traction coefficient, (3) scuffing resistance, (4) wear resistance, and (5) micropitting propensity. While viscosity versus temperature data are readily available, the above five properties or attributes must be measured under relevant conditions for aero propulsion hardware systems. This document (ARP6156) describes the test method for scuffing and wear resistance. It should be noted that the test method results are limited to the selected test conditions, which may not be representative of the broad scope of conditions encountered in service.
