This publication provides a uniform and easily understood system for showing which product/grade of fuel is in each part of an aviation fuel handling system. An effective aviation fuel handling equipment marking system for product identification can help to promote safe and efficient manufacturing and marketing operations, including to prevent delivery of the wrong product or grade of fuel into an aircraft, which may result in engine failure during flight.

This tenth edition includes new recommendations for the marking of equipment to be used with:

− aviation gasoline (avgas) grades UL91 (red banding) and UL94 (purple banding),

− synthetic blending components (SBC) for jet fuel, and

− fuel system icing inhibitor (FSII) for jet fuel and avgas.

It also deletes the former identification system for four grades of avgas that are no longer commercially produced and includes new figures illustrating examples of storage tank marking.

This publication will be of use to those involved in the design, construction, commissioning, operation or maintenance of aviation fuel handling systems, including:

− Airport depots.

− Airport fuel hydrant systems.

− Aircraft fuelling equipment.

− Dedicated grade aviation fuel storage tanks and piping within terminals or manufacturing facilities.

− Dedicated grade aviation fuel loading facilities at manufacturing facilities, terminals or airports, etc.

The marking and colour-coding system is recommended for worldwide adoption.
