ARMY OIL ANALYSIS PROGRAM
The Army Oil Analysis Program (AOAP) analyzes equipment lubricant condition
to detect impending component failures through periodic evaluation of oil
samples. Oil analysis provides a diagnostic tool to determine the interval
conditions of engines, gear boxes, transmissions, and other oil-lubricated
systems and components.
For policies, objectives, and responsibilities
concerning the AOAP, refer to Army Regulation (AR) 750-22.
For detailed
procedures, refer to Technical Bulletin (TB) 43-0210.
The purpose of the AOAP is to-
Detect potential component failure.
Determine oil serviceability and necessity for oil change.
Extend oil life and conserve resources.
Reduce maintenance costs through preventive maintenance prior to major
repair.
Develop a data bank relating to component wear or failure.
DESCRIPTION
Oil analysis is used as a diagnostic tool to determine the physical
condition of used oil and the internal condition of engines, gear boxes,
transmissions, and hydraulic systems.
Spectrometric analysis is used to determine the concentration of various
wear metals in oil samples. Wear metals are metal particles of microscopic
size, produced by the friction of moving parts within mechanical systems,
that enter the oil stream and are dispersed and suspended throughout the
lubricating oil system. The kinds of metal particles and the quantities in
which they are present are detected by spectroscopy.
Analysis helps
determine which component parts may have generated the particles.
By
periodically sampling and testing the oil from mechanical systems, abnormal
wear can be detected and worn parts can be repaired or replaced before they
cause damage.
