WebUVA-340: The UVA-340 provides the best possible simulation of sunlight in the critical short wavelength region from 365 nm down to the solar cutoff of 295 nm. Its peak emission is at 340 nm UVA-340+: The UVA-340+ lamp delivers the same light spectrum as the UVA-340 lamp, plus extended lifetime at high irradiance. WebFluorescent UV test chambers are commonly used for weathering tests of durable polymeric materials. UVA-340 type lamps are a good match to the noon summer sunlight spectrum from the cut-on (295 nm) to approximately 350-360 nm What are the best test conditions for achieving the same dosage of UV radiation as a backsheet would see in 1 year? WebThe specimens will be mounted in the middle of the chamber and the size of the specimens are 120 mm x 50 mm x 6 mm and will be mounted vertical in the chamber. The UV lamp wattage is 30 W.
