Motions Committee Report (NITMAM)
Proposed NFPA documents will be presented for action at the applicable Annual (June) Association Technical Meeting only when proper Amending Motions (Notice of Intent to Make a Motion - NITMAM) have been certified by the Motions Committee of the Standards Council as a proper amending motion. Documents that receive no motions will not be presented at the meeting and instead will be forwarded directly to the NFPA Standards Council for action on issuance. More about the codes and standards making process including NITMAM.

Proposed Tentative Interim Amendment
Proposed Tentative Interim Amendment
Tentative Interim Amendments (TIAs) proposed to the NFPA are published for public review and comment and also forwarded to the responsible Technical Committee and Technical Correlating Committee for processing.

Anyone may submit a comment on a proposed TIA by the closing date indicated below. To submit a comment (on company letterhead), please identify the number of the TIA and forward to the Secretary, Standards Council, 1 Batterymarch Park, Quincy, MA 02169-7471.

The Technical Committee considers comments received by the date indicated before final action is taken on the proposed TIA. The Standards Council then reviews the technical committee's ballot results, the public comments, and any other information that has been submitted to determine whether to issue the TIA. Anyone wishing to address the Council should contact the Codes and Standards Administration Department.

A TIA is tentative because it has not been processed through the entire codes- and standards-making procedures. It is interim because it is effective only between editions of the document. A TIA automatically becomes a proposal of the proponent for the next edition of the document. As such, it then is subject to all of the procedures of the codes- and standards making process.
