UV Fluorescent Lamp Weathering Testing
topic
UV fluorescent lamp chambers use UVA-340 or UVB-313 lamp types to irradiate fabric specimens at defined UV intensities with alternating condensation humidity cycles at elevated temperatures; UVA-340 lamps best simulate the solar UV spectrum below 360 nanometres while UVB-313 provides accelerated degradation rates through enhanced short-wavelength UV exposure.
Role
Provides a cost-effective alternative to xenon arc weathering for photodegradation screening of polymers, dyes, and UV stabiliser treatments in textile materials, particularly useful for ranking relative UV stability and optimising stabiliser concentrations in early-stage product development.
