NATO Standards and other documents
NSPA requirements often include or relate to NATO Standards or publications. For NATO standards publications (Standardization Agreements (STANAG), Allied Quality Assurance Publications (AQAP), etc.), see General Quality Assurance Provisions.
The NATO codification system is the standard way of identifying spare parts, components and supplies within NATO as well as many non-NATO nations that have been joining the system. More information is available under www.nato.int/codification
