Summary of Topics

This reaffirmation of ANSI/UL 489B dated August 26, 2025 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.

As noted in the Commitment for Amendments statement located on the back side of the title page, ULSE and CSA are committed to updating this harmonized standard jointly. However, the revision pages dated August 26, 2025 will not be jointly issued by ULSE and CSA as these revision pages only address UL ANSI approval dates.
