Focusing on solutions
A laser can provide many technological benefits to a product but also adds some additional concerns for safety—laser radiation can be hazardous to the eyes or skin under certain circumstances. The primary purpose of two laser product safety standards—FDA/CDRH 21CFR in the United States and IEC 60825-1 outside the United States—is to make sure a product has appropriate safeguards to protect those who use, maintain and service that product.
UL’s full-service laser laboratories can test products to laser safety requirements and provide the needed report format to meet U.S. FDA/CDRH and/or IEC laser safety standards.
Understanding diverging requirements
As the use of LEDs and their capabilities grow, so do the photobiological safety concerns associated with them. Both the ANSI-based RP-27 and IEC 62471 series of standards address the photobiological hazards from LEDs. UL can perform the testing and evaluation needed to determine a product’s Risk Group hazard classification as defined in the applicable standards.
UL’s optical radiation laboratories can perform evaluations on all types of LED-based products, whether they are LEDs used in bar code imaging or lighting products. Our reports help manufacturers confirm and document compliance with LED radiation safety requirements.
Revealing answers to invisible hazards
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.
