Fire Ratings of Archaic Materials and Assemblies

摘要

The purpose of the report is to assist architects, engineers, preservationists,and code officials in evaluating the fire safety of older buildings by providing documentation on the fire-related performance of a wide variety of archaic building materials and assemblies, and, for those cases where documentation cannot be found, by providing ways to evaluate general classes of archaic materials and assemblies. The term 'archaic' encompasses materials and assemblies typical of an earlier time and no longer in common use. 'Fire-related performance' includes fire resistance, flame spread, smoke production, and combustibility.
