Basically, the aging test methods are carried out by accelerating tests (cycling the exposure of UV light, physical mechanics, like fatigue or crack propagation, water, freeze-thaw, salt spray, etc). I really intrigue is there an official full description or standard method for completely determining the life-cycle of the composite materials for building structure. How correlations test methods' to the time? It would be perfect to give me feedback and ask me closer about my issues by direct message!
