本文件规定了箔片推力轴承性能评估结果的比较方法，箔片推力轴承支持由驱动轴旋转产生的空气动力，并使用空气而非润滑油进行润滑。本文件中解释的试验程序测量和评估了箔片推力轴承的静载荷能力、轴承扭矩、摩擦系数和寿命，并将试验结果与不同试验条件下的结果进行了比较。根据所用测试设备的性能，测得的静态负载能力可能会有所不同。

This document specifies the method for comparing performance evaluation results for a foil thrust bearing that supports load with aerodynamic force generated by the rotation of a driving shaft and lubricates using air, not lubricating oil. The test procedure explained in this document measures and evaluates the static load capacity, bearing torque, friction coefficient and lifetime of the foil thrust bearing and compares the test results to those for different test conditions. The measured static load capacity can be varied depending on the capabilities of the test device used.
