Direct answer
Flammable finishes is a defined term in the International Fire Code (IFC) 2009, in Flammable Finishes. The code's own words are: “Material coatings in which the material being applied is a flammable liquid, combustible liquid, combustible powder or flammable or combustible gel coating.” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 6 chapters of this corpus, most often in Definitions (IFC 2009), Flammable Finishes (IFC 2009), Special Detailed Requirements Based on Use and Occupancy (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.
