What is NFPA 269?
NFPA 269: Document Scope
1.1* Scope. 1.1.1 This test method is intended to provide a means for assessing the lethal toxic potency of combustion products produced from a material or product ignited when exposed to a radiant flux. 1.1.2 This test method has been designed to generate toxic potency data on materials and products (including composites) for use in fire hazard analysis. It is also permitted to be used to assist in the research and development of materials and products. 1.1.3 Lethal toxic potency values associated with 30-minute exposures are predicted using calculations that employ combustion atmospheric analytical data for carbon monoxide, carbon dioxide, oxygen (vitiation), and, if present, hydrogen cyanide, hydrogen chloride, and hydrogen bromide. The calculation method is therefore limited to those materials and products whose smoke toxicity can be attributed to these toxicants. 1.1.4 Specimens are exposed to a radiant heating flux with an electric spark ignition. 1.1.5 Specimens tested are representative of finished products, including composite and combination systems. 1.1.6 This standard is not intended to address all safety issues associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations (especially with regard to the institutional care and use of experimental test animals) prior to use. (For specific hazard requirements, see Section 6.1.)
This standard provides a means for assessing the lethal toxic potency of combustion products produced from a material or product ignited when exposed to a radiant flux. Official document scope
What does NFPA 269 address?
The test method provides toxic potency data on materials and products (including composites) for use in fire hazard analysis as well as product research and development.Table Of Contents.

Report on Proposals (ROP)
Report on Proposals (ROP)
Proposals can be submitted for text to be amended or included in NFPA Codes and Standards. Following the Call for Proposals period, the responsible Technical Committee or Panel holds a meeting to consider and act on all submitted proposals. The committee or panel may also develop its own proposals. A document known as the Report on Proposals (ROP) is prepared containing all the Public Proposals, Technical Committees' action on each Proposal, as well as all Committee-generated proposals. The ROP for the document in question is submitted for the approval of the responsible TC or Panel by a formal written ballot. If the ROP does not receive approval via written ballot in accordance with NFPA rules, the Report is returned to the committee for further consideration and is not published. If the necessary approval is received, the ROP is published in a compilation of Reports on Proposals issued by NFPA twice yearly for public review and comment, and the process continues to the next step. The ROP is published and widely distributed and anyone may download or request a copy.

Report on Comments (ROC)
Report on Comments (ROC)
Once the ROP becomes available, there is a 60-day comment period during which time anyone may submit a public comment on the proposed changes documented in the ROP. The committee or panel reconvenes at the end of the comment period and acts on all public comments. This committee or panel may also develop its own comments. As before, approval obtained via written ballot in accordance with NFPA's Regulations is required on all committee and panel actions. All of this information is compiled into a second Report, called the Report on Comments (ROC), which like the ROP, is published and made available for public review for a seven-week period.

Motions Committee Report (NITMAM)
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.
No NITMAMs

Tentative Interim Amendment (TIA)
Tentative Interim Amendment (TIA)
Tentative Interim Amendments (TIAs) are amendments to an NFPA document processed in accordance with Section 5 of the Regulations Governing Committee Projects. They have not gone through the entire codes and standards-making process of being published in a ROP and ROC for review and comment. TIAs are 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 is then subject to all of the procedures of the codes and standards making process. TIAs are published in NFPA News , NFCSS, and any further distribution of the document after being issued by the Standards Council.

Requests for TIAs shall be clearly worded to provide the recommended revision and the reason as to why it is of an emergency nature requiring prompt action. Submissions shall be in writing, addressed to the Standards Council Secretary, NFPA, 1 Batterymarch Park, Quincy, MA 02169-7471. The submitter must also provide the appropriate endorsments in writing of two members of the applicable technical committee or technical correlating committee. For further information on submitting a TIA, please contact Codes and Standards Administration.
