Purpose
UV weathering chamber adopts fluoresvent UV lamps as light sources to perform accelerated weathering test on materials by means of simulating ultraviolet radiation and condensation of nature's sunshine,so as to know about the weather ability of materials This machine is apply to nonmetal material, organic material (like paint coating. rubber, plastic and products made in these materials) .
Standards
GB/T14522-93,GB/T16422.3-1997,GB/T16585-96 etc.
Light Source
1, Using 8pcs UV fluorescent lamps with 40W power rating as light source. UV fluorescent tubes are distributed on both sides of the machine, each side has 4pcs. It has UVA-340 and UVB-313 optional for customers' configuration. (Option one type)
2, UVA-340 lamp luminescence spectra energy is mainly concentrated in the 340nmof wavelength.
3, UVB-313 lamp luminescence spectra is mainly concentrated near the 313nm of wavelength.
4, Due to fluorescent light energy output will gradually decay over time, in order to reduce the test effect because of light energy attenuation, when in every 1/4 of the fluorescent lifetime of eight lamps in the chamber, a new lamp will replace an old lamp, thus UV light source is always formed by new lamp and old lamp, to get a constant output of light energy.
5, the effective useful life of the lamp is about 500 hours (imported one is about 1600~1800 hours).
