Natural Outdoor Weathering and Exposure Testing
topic
Natural outdoor weathering exposes fabric specimens on standardised racks at defined tilt angles and compass orientations at reference exposure sites including Florida, Arizona, and temperate European locations, collecting total radiant exposure in megajoules per square metre alongside meteorological data to enable correlation of degradation with dosed irradiance.
Role
Provides the ground truth service life data against which accelerated weathering chamber results are calibrated, enabling development of acceleration factors that allow realistic outdoor durability prediction from condensed laboratory exposure programmes for outdoor textiles and geosynthetics.
