The Metallic Materials Properties Development and Standardization (MMPDS) Handbook, is an accepted source for metallic material and fastener system allowables recognized by the Federal Aviation Administration (FAA), all Departments and Agencies of the Department of Defense (DoD), and the National Aeronautics and Space Administration (NASA) within the limitations of the certification requirements of the specific government agency.

This chapter, while comprising three major parts, primarily is concerned with joint allowables. Part 8.1 is concerned with mechanically fastened joints; Part 8.2, with metallurgical joints (various welding and brazing processes). Part 8.3 contains information for structural component data; it is concerned with bearings, pulleys, and cables.
