Addenda Indexes for Standards 34, 62.1, and 90.1

New editions of ASHRAE Standards are published which incorporate any addenda that have been approved for publication since the previous edition. Addenda to previous editions that have not yet been approved for publication are then re-lettered to identify them to the latest edition. This re-lettering of addenda may not occur until such time as the responsible project committee approves the addendum for a subsequent public review or for publication ('TBD'- To Be Determined). In some cases, the addendum letter will remain the same and only the year will change. Click on the applicable standard below to see an 'Addenda Index' that will provide a cross-reference to the previous edition. Copies of these addenda are available only during the public review draft period and these addenda are only available for comment during this same period.
