What we do

UL engineers scientifically investigate and test thousands of types of products, materials, constructions and systems to evaluate the electrical, fire and injury risks; the burglary or fire resistance; or the ability to detect, control or limit fires. We test the latest products and breakthrough technologies for safety before they go to market around the world. Regardless of where you are based, as a UL engineer your work has global impact.

Standards for Safety

UL has developed 1,200 Standards for Safety, which serve as the bedrock of compliance in over 200 industries. Our Standards are developed using an open, consensus-building process. We include input from consumers, manufacturers, government agencies, users, regulator authorities and other interested parties to build today's most effective product safety standards.

Inspection services
