Summary of Topics

This revision of ANSI/UL 5085-2 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 and CSA are committed to updating this harmonized standard jointly. However, the revision pages dated November 29, 2017 will not be jointly issued by UL and CSA as these revision pages only address UL ANSI approval dates.
