This revision of ANSI/UL 248-16 is being issued to reaffirm approval as an American National Standard. No changes in requirements are involved.
As noted in the Commitment for Amendments statement located on the back side of the title page, UL, CSA, and ANCE are committed to updating this tri-national standard jointly. However, the revision pages dated November 3, 2008 will not be jointly issued by UL, CSA, and ANCE as these revision pages address only UL ANSI approval dates.
