Air Force Corporate Standards
Installations are required to establish and maintain exterior sign standards under Installation Facilities Standards (IFS). Provide visual and functional consistency, maximize durability and minimize maintenance requirements while ensuring a quality professional appearance. Limit the number of signs to the absolute minimum to lower costs and reduce visual clutter. Coordinate historic signs through the state historic preservation office (SHPO). Judiciously replace non-conforming signs to meet current standards.
Coordinate design and selection of materials to ensure components comply with applicable policies. Use environmentally responsible materials, finishes and coatings for sign elements.
