    UL STANDARDS: ACCREDITED IN THE US AND CANADA

    In the US, UL is accredited by the American National Standards Institute (ANSI) as an audited designator. In 2013, UL was accredited by the Standards Council of Canada (SCC) as a nationally recognized Standards Development Organization (SDO) able to develop National Standards of Canada (NSCs).

    UL's Standards Technical Panels (STPs) serve as the consensus body for both American National Standards (ANS) and National Standards of Canada (NSC). Essential information About UL's standards development programs, how to Access Standards, and how to participate in the UL programs used to Develop Standards is available on this site.

    Visit UL Standards for Canada for information on UL's development of National Standards of Canada (NSCs) and about specific projects under New Project Activity, Public Review and Work Programs.
