If you read this paragraph in a vacuum, it seems like all fire doors have to limit the air infiltration to this level (in most cases this would require gasketing), but this paragraph falls under section 716.5.3 – Door assemblies in corridors and smoke barriers. There are two sections following 716.5.3 that apply to other types of fire doors…
