Excerpt from Usda Forest Service General Technical Report: Int 181-185 In the course of conducting research, chemical procedures have been devel oped for measuring quantitatively the concentrations of many of these Compo nents. Based on these analyses, simple field test methods for determining salt content have been devised and calibration tables developed relating properties such as specific gravity to the actual retardant salt content. Although such field procedures have been developed and are being used operationally, there is often a need to analyze for specific fire retardant ingredients. In most of the specific analyses, the fundamental method is not new, but specific conditions, operations, and procedures have been developed to yield optimum results with normal mixtures of ingredients present in fire retardants. There is an increasing need to determine the concentration of various retardant ingredients as well as the level of retardant coverage in specific laboratory and field research or administrative studies.
