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.
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.
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.
