Tentative Interim Amendments, Errata, and Formal Interpretations

Tentative Interim Amendments

Tentative Interim Amendments (TIAs) are amendments to an NFPA standard processed in accordance with Section 5 of the Regulations Governing the Development of NFPA Standards. TIAs have not been published in a First Draft Report and Second Draft Report for review and comment.  An issued TIA automatically becomes a Public Input for the next edition of the standard, and is then subject to all of the procedures of the standards development process. TIAs are published in NFPA News, the National Fire Code Subscription Service, and any further distribution of the standard after being issued by the Standards Council. 

Requesting a TIA
To request a TIA, download and complete a Tentative Interim Amendment request form. Include a statement of the problem and a reason for the emergency nature requiring prompt action. Also, provide written agreement to the processing of the submitted TIA of two members of the applicable Technical Committee or Correlating Committee. Completed forms can be forwarded to the Secretary, Standards Council

Proposed TIAs
Proposed TIAs are published for public review and comment, and are forwarded to the responsible Technical Committee and Technical Correlating Committee for processing. The Technical Committee considers comments received before final action is taken on the proposed TIA. The Standards Council then reviews the Technical Committee's ballot results, public comments, and any other information that has been submitted.  Anyone may submit a comment on a proposed TIA. To submit a comment, please identify the number of the TIA and forward to the Secretary, Standards Council by the closing date listed below.
