First of two simultaneous responses --

Step 1 is to get the best fade resistant dye (they have ratings) and then give it an excellent seal.

I am not aware of a global test for fading, but you could design your own by using test cells with intense fluorescent lamps and another with a xenon lamp.

Consider ASTM G23, ASTM G26, or ASTM D822. These are the test methods specified by MIL-A-8625 / MIL-PRF-8625 [⇦ this spec on DLA] for light fastness evaluation.
