Broadband ultraviolet (UV) radiation can be emitted by LEDs or lamps, depending on their purpose. UV radiation is primarily invisible and can present a photobiological safety concern to the eyes and/or skin of those exposed to it.
There are several safety standards that address the hazards from UV radiation, including the ANSI-based RP-27 series, the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit values for occupational and environmental health requirements, and the IEC 62471 series of standards. UL’s optical radiation laboratories can evaluate UV radiation to any of these standards. Results are provided in the appropriate reporting format, facilitating quick access to target markets.
