The test fixture shall operate at 5 0.2 volts co
10、ntinuously for a period of 300 hours at room ambient. At the completion of this test, the colors must remain within the limits specified in table I. The color fade test fixture shall consist of one MIL-PRF-22885/10 or MIL-PRF-22885/16 modular indicator light for each color of filter to be tested, mo
