UL 482:2020 PDF Download

UL 482:2020 is a standard that specifically addresses portable sun/heat lamps. The standard covers sun lamps, heat lamps, and combination sun and heat lamps that are rated at no more than 125 V. A sun lamp is designed to produce ultraviolet radiation for skin tanning, while a heat lamp is intended for the production of infrared radiation. A combination sun and heat lamp is capable of producing both ultraviolet and infrared radiation. It should be noted that the term "sun/heat lamp" encompasses all these types of lamps.

This standard applies to portable sun/heat lamps that are intended for use by non-technically qualified individuals in various settings, such as homes, sports facilities, health spas, and similar establishments. These lamps are designed to be connected to a power-supply circuit via a flexible cord and are expected to be used in accordance with the National Electrical Code (ANSI/NFPA 70).

However, it's important to clarify that this standard does not cover lamps primarily used for illumination, although some visible radiation may be emitted during the operation of a sun/heat lamp. Additionally, the standard does not cover sun or heat lamps intended for professional use. These professional use lamps are designed for technically qualified individuals in medical establishments and are subject to the requirements for medical and dental equipment.

Furthermore, if ultraviolet lamps are intended for high-intensity, short-duration operation (with a maximum first exposure time of 2 minutes for sensitive skin), they will undergo an appropriate investigation to determine any additional requirements that may be applicable for this specific feature. Lastly, it is worth noting that this standard applies to complete appliances and not just the bulbs themselves.
