What is NFPA 203?
NFPA 203: Document Scope
1.1 General. 1.1.1 The term roof covering refers to the material or the combination of materials applied on top of the roof deck for weatherproofing and can include insulation. 1.1.2 Since most roof coverings are combustible to some degree, they could be vulnerable to external fire exposure. Some roof coverings propagate a rapidly spreading fire over the surface or allow the fire to penetrate the roof covering and to communicate to the interior of the building and need to be avoided. 1.1.3 Roof coverings over metal and some other decks also should be considered for their possible contribution to fire spread originating on the interior of the building. The heat of the interior fire rises to the ceiling and can cause the liberation of combustible gases and flaming droplets through the joints, overlaps, and distortions of the deck. This can contribute significantly to the fire by means of flame spread beneath the roof and ignition of combustible contents by means of burning droplets of flowing materials. 1.1.4 A wide variety of roof coverings and roof deck constructions have been fire tested and listed by testing laboratories with respect to their characteristic behavior when subjected to both external and internal fire exposure. 1.1.5 Precautions should be taken during the installation of roof decks or coverings and above-deck components to prevent fire.

NFPA 203, 2000 Edition: Archived Revision Information
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.
