This document contains the results of work performed to evaluate properties of foams used for fire exposure protection. The scope of this effort is to establish a testing procedure to evaluate the relevant properties of fire exposure protection foams. There are many different types of foams on the market. Most of the foams are used for fire suppression, but this study focusses on those intended to be used for fire exposure protection. Five foams were selected, all commercially available. Each comes in a concentrated liquid which is diluted in water and mixed with air to form a protective coating. Four of the foams chosen are synthetic hydrocarbon based. The fifth is a protein based foam manufactured from raw animal protein sources. All five foams are generated and tested in identical manners to observe their individual fire exposure protection characteristics. The four synthetic foams are identifed as Foams A, B, C, and D and the protein based foam is identified as E.
