This volume was prepared under the technical cognizance of the Joint Oil Analysis Program Technical Support
Center, Pensacola, Florida. Comments and recommendations pertaining to this volume should be submitted in
accordance with instructions in paragraph 1-6.
1-1. Purpose. The Joint Oil Analysis Program (JOAP) was established by the Joint Army, Navy and Air Force
regulation as a combined effort to establish and maintain a standard program that would consolidate and coordinate
the three separate service oil analysis programs. The purpose of Volume I is to clarify the use of oil analysis as a
diagnostic maintenance tool, to standardize JOAP operating procedures and to provide general guidance for JOAP
managers and customers in accordance with the Tri-Service Regulation (AFI21-131(I)/AR700-132/OPNAVINST
4731.1B). Specific JOAP Laboratory operating procedures and guidance are contained in Volume II. The JOAP
equipment wear-metal criteria listings which contain trend tables and decision making guidance for laboratory use in
evaluating oil sample analysis results and determining actions required are contained in Volumes III and IV for
aeronautical and non-aeronautical equipment, respectively.
1-2. Applicability. The provisions of this volume apply to all activities of the Departments of the Army, Navy, Air
Force and the Coast Guard participating in the JOAP and to laboratories operating under contracts therewith.
Laboratory services provided by JOAP laboratories to customer activities will be in accordance with instructions
contained in this manual.
