Examples of interfaces (e.g., for mechanical or electronic components) that can be classified within these three classes include the following:

·       Mechanical interfaces (e.g., weight and size, center of gravity, clearance of parts in operation, space required for maintenance, fixed links, mobile links, shocks and vibrations received from the bearing structure)

·       Noise interfaces (e.g., noise transmitted by the structure, noise transmitted in the air, acoustics)

·       Climatic interfaces (e.g., temperature, humidity, pressure, salinity)

·       Thermal interfaces (e.g., heat dissipation, transmission of heat to the bearing structure, air conditioning characteristics)

·       Fluid interfaces (e.g., fresh water inlet/outlet, seawater inlet/outlet for a naval/coastal product, air conditioning, compressed air, nitrogen, fuel, lubricating oil, exhaust gas outlet)

·       Electrical interfaces (e.g., power supply consumption by network with transients and peak values; nonsensitive control signal for power supply and communications; sensitive signal [e.g., analog links]; disturbing signal [e.g., microwave]; grounding signal to comply with the TEMPEST standard)

·       Electromagnetic interfaces (e.g., magnetic field, radio and radar links, optical band link wave guides, coaxial and optical fibers)

·       Human-machine interface (e.g., audio or voice synthesis, audio or voice recognition, display [analog dial, liquid crystal display, indicators' light emitting diodes], manual controls [pedal, joystick, track ball, keyboard, push buttons, touch screen])

·       Message interfaces (e.g., origination, destination, stimulus, protocols, data characteristics)
