Our consensus standards for safety are developed in collaboration with experts representing a broad range of interests and perspectives.



Underwriters Laboratories is a standards-setting organization, combining extensive safety research, scientific expertise and input from stakeholders to advance safety science that leads to safe living and working environments. Underwriters Laboratories develops and publishes consensus standards that guide the safety, performance and sustainability of new and evolving technologies and services to deliver solutions for industries from household appliances to smoke alarms to batteries to environment to cybersecurity to building materials.
Delivering Standards for Safety, Performance, and Sustainability

Safety standards are documents that outline the process through which a product or service is tested and evaluated to confirm its compliance with requirements that help mitigate risk, injury or hazards. Since publishing its first standard in 1903, Underwriters Laboratories has developed more than 1,700 UL and ULC standards. In extending its global public safety mission, Standards partners with national and regional standards bodies in countries around the world to build a safer, more sustainable world.

Accredited Standards Developers in Canada and the U.S. 

Underwriters Laboratories is proud to be an accredited standards developer in Canada and the U.S. and authorized to develop national standards for Mexico. This means that we are able to develop standards to advance safety, performance and sustainability to meet stakeholder needs and bridge standards development gaps across much of North America. 

Our Stakeholders

Stakeholders are essential to the development of UL standards through their service on ULC Technical Committees and UL Standards Technical Panels (STPs). These diverse stakeholders include manufacturers, retailors, consumers, trade associations, regulators and other authorities along with other varied and vested interests. This participation enables diverse interests to provide input, review proposals and meet to discuss issues — all facilitated by UL's non-voting standards development organization. 

We conduct original scientific research and release extensive reports for the benefit of public and private stakeholders.


Our work involves collaborating with stakeholders from around the world who share their expertise to solve challenges related to safety, security and sustainability. We are an accredited, globally influential standards development organization applying research and safety science to keep pace with the rapid advancement of new technology also dedicated to continually evaluating the safety of legacy products and systems. 


UL Standards convenes key stakeholders and decision makers from a wide cross-section of the safety community. We seek to foster relationships and facilitate discussions that improve safety policies and practices around the world.
