In my recent NFPA Live session I answered a few of the most popular questions about NFPA 285, Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components , including when a building requires NFPA 285 compliance. I also discussed some of the revisions being presented at the next Fire Test Committee meeting.


During the live event I received this follow-up question from an NFPA member. I'm now sharing it with you. I hope you find some value in it.
