Correlation between accelerated weathering duration and

A.Correlation between outdoor and artificial weathering devices is very material dependent.Factors that must be considered are light (both quantity and quality),moisture cycles,and temperature.I don't know if 3000 hours is close to 125 months,but that sounds a bit unrealistic.Correlation between accelerated weathering duration and A.Correlation between outdoor and artificial weathering devices is very material dependent.Factors that must be considered are light (both quantity and quality),moisture cycles,and temperature.I don't know if 3000 hours is close to 125 months,but that sounds a bit unrealistic.Color stability of heat-treated wood during artificial The color change of wood after exposure to UV light may produce aesthetical damages.The stability of the color to light exposure is an important issue.This study describes experiments of testing the color stability of heat-treated wood samples.Heat treatment was done at 240 Artificial Weathering#176;C during 2 hours,under nitrogen.Heat-treated samples of ash,beech,maritime pine and poplar heartwood were exposed
