Effect of weathering conditions on wood surface roughness: Optimal parameters determined via Taguchi analysis

Wood when exposed to accelerated weathering conditions is deteriorated as a result of factors such UV rays, temperature, and relative humidity changes. The surface roughness wood also undergoes substantial In this study, the effect on changes Scots pine (Pinus sylvestris L.) poplar (Populus x euroamericana) surfaces were investigated using Taguchi method. parameters most affecting radial direction, 0.5 W/m2 UV, 4 h conditioning time, 45 min water for pine, tangential 2 conditioning, 15 wood. variables that affected with 38% in wavelength 31%
