For more than a century, the UL mark has helped inspire confidence in a product’s safety and quality. For UL, facilitating the standards development process, developing standards and certifying to those standards helps ensure that quality starts at the component level.
UL is a premier global independent safety science company that has championed progress for more than 120 years. By working with industry stakeholders and Standards Technical Panels (STPs), UL develops safety standards across a multitude of industries.
UL has evaluated and certified millions of common electrical products, which bear its famous mark: The letters UL inside of a circle.
