This paper explores four technologies used for testing weathering and light stability of printed materials, giving special attention to those most commonly used today: xenon arc test chambers (ASTM G155, ISO 4892-2), fluorescent UV weathering testers (ASTM G154, ISO 4892-3), and a variant of the fluorescent tester for simulating indoor lighting. The inherent strengths and weaknesses of each tester will be discussed and general guidelines will be given for which tester appropriate for a particular material or application. Spectral sensitivity of materials and the importance of proper units of measure for light intensity will be discussed, leading to conclusions on the difficulties and opportunities that arise from accelerated testing.In this paper, the brand name QUV® will sometimes be used to indicate a fluorescent tester. The brand name Q-SUN® will sometimes be used to indicate a xenon tester. Both brand names are trademarks of Q-Lab Corporation.
