RECENT investigations at the National Bureau of Standards, U.S.A., by S. A. McKee, J. F. Swindells, H. S. White, and Wayne Mountjoy have shown that the SAE extreme‐pressure lubricants testing machine can be adapted to measure accurately the wear obtained with various automotive gear lubricants under simulated service conditions. This apparatus—originally designed for testing load‐carrying capacity of gear lubricants under fixed high‐speed and shock‐loading—provides a sensitive means for the evaluation of lubricants with respect to wear at high torque and low‐speed operation. The new test therefore makes it possible to detect any significant difference in the performance of lubricants meeting the requirements of the same specifications.
