DEFINITIONS PHYSICAL CLASS I:

Flight Assembly Tolerance: Built to flight dimensional specifications.

Similar Material: Materials used are of the same family and are characteristic of the flight material, but not necessarily of the same grade or specification (e.g., metals-metal, plastics-plastic, fabrics-¬fabric).

Exact Configuration: Appearance is like flight in all aspects (e.g., size, shape, color, orientation, location, etc.).

CLASS II:

Relaxed Assembly Tolerance: Not held to flight dimensional specifications. Margins to be specified by program.

Mixed Materials: Materials will be generally characteristic of flight, but not necessarily of the same family, grade or specification. Material should be selected to optimally support the intended function.

Approximate Configuration: Appearance is similar to flight in most aspects (e.g., size, shape, color, orientation, location, etc.).

CLASS III:

Approximate Tolerance: Held to volumetric approximations. Mixed Materials: Materials support facility objectives.
