Meet UL
What does UL test?
UL evaluates more than 19,000 types of products, components, materials and systems annually with 20 billion UL Marks appearing on products from more than 72,000 manufacturers each year. We evaluate everything from electrical appliances and outlets to water and plastics. If it plugs in, it’s probably tested by UL to determine that safety standards have been met. Just as importantly, UL tests many of the materials used to build the places where you live, work and play. As technologies advance, however, and new safety issues arise, we are also verifying environmental claims and leading the way in sustainable product certification.
How does UL test products?
UL has 64 facilities in 27 countries worldwide where we rigorously test and review products for important safety issues such as electrical shock, fire hazards, EMC and even performance when it’s inherent to a product operating safely. Drawing on the knowledge gained from more than 100 years of certifying products and the expertise of approximately 6,800 professionals worldwide, we set the standard in safety around the world, everyday.
