The objects of the study was to evaluate a test kit for the determination of the freezing point of antifreeze solutions in the field. The kit consists of a plastic strip 3-14 inch by 14 inch with a dry reagent pad 1 4-inch square attached to one end. The reagent pad is chemically impregnated so that it changes color when dipped into various concentrations of ethylene glycol. The kit was tested in the laboratory with various antifreeze solutions. It was also tested on the antifreeze in approximately 90 military vehicles.
