Overview
Title:  Guide for Selection of Lubricants, Fluids, and Compounds for Use in Flight Vehicles and Components
Scope:  This handbook establishes design guides for selection of suitable lubricant fluids and compounds, which conform to approved specifications, as required by MIL-STD-838. It includes descriptive material relative to application and limitations of the materials, a list of material specifications together with specific requirements (table I), and a list of the more important specification characteristics (tables II and III). (See pages 18 through 43.) Viscosity-temperatures characteristics of aircraft and aircraft engine oils are shown in figures 1 and 2 (see pages 47 and 48). Lubricant fluids and compounds containing graphite are not preferred for application in new designs and all efforts should be made to select lubricants not containing graphite.
