This test machine provides a rapid method of measuring the load-carrying capacity and the wear properties of lubricants. The test consists of rotating a test pin between two loaded journals (V-blocks) immersed in the lubricant sample. There are two common tests run in this machine: 1.) is an EP test (subjecting a test lubricant to increasing loads until a failure occurs) and the other is, 2.) a wear test (subjecting a lubricant to a constant load for a definite period of time while measuring the wear pattern). A. What is this machine's designation and, B. What ASTM tests are used with machine? Guidelines for the Question of the Day: 1.
