1-1. PURPOSE. Volume IV presents the methodology for evaluating analyses of samples from nonaeronautical

equipment. The methodology enables an evaluator to identify wear-metals present in the sample and their

probable sources, to judge equipment condition, and to make recommendations, which influence maintenance

and operational decisions. Following these recommendations can enhance safvety and equipment reliability and

contribute to more effective and economic maintenance practices. Test procedures are contained in Volume II.

1-2. Applicability. The provisions of this manual apply to all activities of the Departments of the Army, Navy, and

the Air Force participating in the Joint Analysis Program (JOAP) and analyzing nonaeronautical samples. They

also apply to the laboratories operating under contract or mutual assistance agreements therewith.
