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.

Also, provide written agreement to the processing of the submitted TIA of two members of the applicable Technical Committee or Correlating Committee.
