DEFSTAN

DEFSTAN is a term used within the United Kingdom's Ministry of Defence (MOD) to refer to a Defence Standard. These standards are official documents that outline specific requirements for a wide range of products, processes, and services used by the MOD. DEFSTANs cover everything from the materials used in military equipment to the testing procedures for defense systems and the safety regulations for personnel.

The purpose of DEFSTANs is to ensure consistency, reliability, and interoperability across all branches of the British armed forces. By adhering to these established standards, the MOD can guarantee that equipment and services meet the demanding operational needs of defense and that interoperability between different systems and units is maintained. This also aids in procurement, ensuring that suppliers provide goods and services that meet the required specifications.

DEFSTANs are developed and maintained by subject matter experts within the MOD and its associated research and development organizations. They are regularly reviewed and updated to reflect technological advancements, evolving operational requirements, and changes in international standards. Access to DEFSTANs is typically restricted to authorized personnel and organizations involved in defense procurement and operations, although some may be publicly available.
