What is AFQRJOS?

Aviation Fuel Quality Requirements for Jointly Operated It defines the fuel quality requirement for supply into Jointly Operated Fuelling Systems. The aviation fuel quality requirements for jointly operated systems(AFQRJOS) for Jet A11 embodies the most stringent requirement of the following 2 specifications.


• British Ministry of Defence Stan 91-91/issue6 Amendment 1 of 25 Aug 2008 for turbine fuel kerosene. Type    Jet A1 ,NATO CodeF-35, Joint Service Designation AVTUR
• ASTM std specification D 1655-089 for aviation Turbine Fuels.

Jet fuel that meets the AFQRJOS is usually referred to as "Jet A-1 to Check List", or "Check List Jet A-1" .
