The revision of ANSI/UL 60745-2-21 dated September 4, 2019 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, UL and CSA are committed to updating this harmonized standard jointly. However, the revision pages dated September 4, 2019 will not be jointly issued by UL and CSA as these revision pages address UL ANSI approval dates only.
