9.    What is the difference between UL Certified, UL Classified, UL Listed and UL Components?

Whether Classified, Certified or Listed, when you see a UL Mark on a product that means that the product has met scientific safety, quality or security standards. The UL certification Mark can be found on items ranging from hoverboards to lightbulbs to smoke alarms. The UL Listed Mark can be found on furnaces and heaters, fuses, electrical panels, fire extinguishers and more. The UL Classified Mark is featured on products that have been evaluated for a specific hazard or performance under specific conditions, like bullet-resistant glass. The UL Recognized Component Mark is used on components that are part of a larger product or system, like a wiring board for a computer or a motor for a fan.
