API Std 1542

This publication is intended to provide a system for marking aviation fuel types and grades on fuel-handling installations and equipment.

In addition to the requirements for proper marking and colour-coding, there is a need throughout the aviation industry, in general, for uniformity in product labels. The aviation gasoline (Avgas) and turbine fuel (Jet Fuel) labelling system included herein for aviation use is recommended for worldwide use, not only for aviation fuel handling equipment at airport fuel storage facilities, but for all situations where it is desirable to identify Avgas and Jet Fuel by type and grade. It is intended to apply to equipment that is in continuous use for a single grade of aviation fuel, e.g.:

• Airport depots.
• Airport fuel hydrant systems.
• Airport fuelling vehicles.
• Dedicated grade aviation fuel storage tanks and piping within terminals.
• Dedicated grade aviation fuel loading facilities at refineries, terminals or airports, etc. It is not intended to apply to equipment that is not in continuous aviation fuel use, e.g.:
• Refinery storage tanks and associated piping.
• Multi-product pipelines.
• Non-dedicated loading facilities, etc.

For further information on labelling systems for equipment not in aviation use see the latest edition of either API RP 1637 Using the API color-symbol system to mark equipment and vehicles for product identification at service stations and distribution terminals, or IP Code of practice for a product identification system for petroleum products.
