Use of the SD-18 "Parts Requirements and Application Guide", and the associated SD-18 database hosted at the NAVSEA web site, during the design selection process of commercial parts will help ensure the selection of the right commercial parts in terms of the right quality, reliability and cost which will improve overall performance and mission success at reduced cost.
SD-18 "Parts Requirements and Application Guide" provides guidance when using military and commercial parts in military environments. It provides part acquisition guidelines for Program Managers, System Program Offices, and Original Equipment Manufacturers. SD-18 provides guidance on how the Department of Defense and its contractors can cooperatively select devices that will result in the lowest cost of ownership for the DoD. This was prompted by the many changes during acquisition reform in the 1990s. The use of commercial parts and documents has increased in today's military system applications. Because the parts are not as fully characterized as the traditional military parts have been in the past, the design implications of using these parts are not well understood. Commercial parts, often have advantages in cost, size, weight, performance and availability, have attracted widespread attention for government and military applications. It is critical that we do not jeopardize performance of our weapons systems when selecting commercial parts. This guide can help in the selection of these devices.
This document is sponsored by the Defense Standardization Program Office. Several years ago SD-18 evolved from a now canceled NAVSEA "Parts Requirements and Application Manual" TE000-AB-GTP-010 document. SD-18 is a web based only document as part of the paperless document approach.
The SD-19 Parts Management Guide - In today's acquisition environment-characterized by rapidly changing designs, increased risk for Department of Defense (DoD) weapon systems and equipment acquisition contracts due to an increase in the use of commercial part types, offshore manufacture of parts, and Diminishing Manufacturing Sources and Material Shortages (DMSMS)-the need for contractors to have an effective Parts Management Program (PMP) is greater than ever before. The PMP is an integral part of the acquisition process for design, development, modification, and support of weapon systems and equipment.
