fluorescent uv lamps, similar in mechanical and electrical characteristics to those used for residential and commercial lighting, have been developed with specific spectral distributions. Tests using fluorescent lamps are useful for relative rank comparisons between materials under specific conditions, but the comparison to service lifetime performance or correlation to outdoor exposures may not be valid. The best use of the uv lamps is for general screening tests, such as checking for gross formulation errors with an artificially harsh exposure.
the atlas uvtest is designed for economical weathering testing with the sophistication of atlas' 90 years of weathering expertise. Innovative design features improve test reproducibility and lower operating costs while testing a variety of materials for their reaction to uv, temperature and moisture.
