The Qualified Products Database (QPD) contains qualification information regarding products and manufacturers, as compiled and maintained by the individual Qualifying Activities (QA). One of the primary goals of QPD is to create an on-line replacement for paper-based QPL/QML documents and provide buyers with the assurance that listed items currently comply with specified requirements. Information is more current more quickly when Haystack uses XML processing to draw from the QPD rather than published PDF documents. Once you view the document online in Haystack, you can still download a PDF, which is processed after the document is pulled from QPD.
The QPD database provides cross-references to the Haystack Master Cross-Reference List (MCRL) data by part number. Information on Standard Military Drawing (SMD) part numbers is also included.
