Reference Oil C Status Report-1970.
Abstract
A summary of the gear load-carrying capacity of Reference Oil C, determined by from six to eight cooperating laboratories using Ryder gear machines, WADD gear machines, and AFB gear machines, is presented. Based upon 916 determinations obtained during a 4-yr period using the three different machine types, the overall mean load-carrying capacity for Reference Oil C is shown to be 2957 lb/inch. A possible difference, at the 95 percent is confidence level, in the load-carrying capacity obtained using test gears with different gear letter prefixes is indicated. This possible difference in test gears, however, is overshadowed by the wide spread, 474 lb/in., in the mean load-carrying capacities obtained by the different laboratories. Inspection data for Reference Oil C, recorded semiannually for a period of 5 yr, does not indicate any significant change in viscosity, neutralization number, API gravity, saponification number, water content, trace sediment, or contamination.
