This revision of ANSI/UL 248-4 dated March 20, 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.
As noted in the Commitment for Amendments statement located on the back side of the title page, ULSE, CSA and ANCE are committed to updating this harmonized standard jointly. However, the revision pages dated March 20, 2024 will not be jointly issued by ULSE, CSA and ANCE as these revision pages only address UL ANSI approval dates.
