Army Oil Analysis Program for Vehicle Testing
Abstract
SCOPE. This TOP describes the procedures for conducting oil analysis during vehicle testing to include the following: Physical Property Tests: water contamination, viscosity, acid/base number, fuel contamination by Fourier Transform Infrared (FTIR) Analysis. Particle Count Analysis: on hydraulic fluid used in hydraulic systems. Spectrometric Oil Analysis: wear metals in lubricating oil, additive packages depletion, identification of other non-metal contaminants such as silicon and sodium. Ferrography: identification of wear metal particles for characterization (type of wear), foreign contamination (grease, coal, asbestos, carbon flakes), and quantitative analysis (wear particle concentration of large size particles to small size) to evaluate accelerated wear preceding component failure. Fourier Transform Infrared Analysis: identification of oil type, monitoring additive package depletion, contamination by water, fuel, antifreeze, monitoring soot buildup and oil degradation. Oil analysis information provides interval monitoring of the quality of the oil taken from various fluid-wetted components. Results will aid in the early detection of impending failures. Overall oil analysis information collected can be incorporated into the Army Oil Analysis Program (AOAP) groundwork for establishing routine testing criteria and sampling intervals for a specific vehicle or vehicle type.
