This reaffirmation of ANSI/UL 61058-1-1 dated December 17, 2024 is being issued to update the title page to reflect the most recent designation as a Reaffirmed American National Standard (ANS). No technical changes have been made.

UL 61058-1-1 is an adoption of IEC 61058-1-1, First Edition, issued by the IEC May 2016. Please note that the National Difference document incorporates all of the U.S. national differences for UL 61058-1-1.
