UL/cUL Compliance and Adoption Program

What is UL and cUL Recognition?


For a label material to have UL recognition, it must pass a series of durability tests and remain legible. The testing includes exposure to a range of temperatures, as well as exposure to various chemicals, including cooking oil, motor oil, laundry detergents, cleaning solutions and gasoline, along with many other solvents and chemicals. Materials must also pass abrasion testing and remain legible.
