Griffiths, D.J., 1973. A LABORATORY BURN-BACK TEST FOR FIRE FIGHTING FOAMS. Fire Research Notes 975
This note describes the development of a laboratory scale burn-back test. The effects of changes in the properties of the foam on its burn-back resistance have been investigated and the results used to produce a standard test method. This method has been used to compare eight commercially-available foam liquids, and to determine the compatibility of fluorochemical and protein foams with reference to their burn-back resistance.
