MARK IIA Aqueous Film Forming Foam (AFFF) Precision Metering System ProductEvaluation Test Report

摘要

Final report of the commercial technology exploitation evaluation of a computercontrolled AFFF metering system produced by NORDIC Systems Inc. of Toronto, Canada. The initial evaluation was conducted by Wright Laboratory, Airbase Fire Protection and Crash Rescue Systems section at Tyndall AFB, Florida between 16 December 1992 and 25 June 1993. This initial evaluation used paddle wheels to determine liquid flow rates, but resulted in irregular concentrations of foam. A follow-on evaluation incorporating magnetic flow meters was conducted between 7 and 9 November 1994. The test evaluated foam concentrations of 1, 3 and 6 percent. The system met user requirements and has been recommended for retrofit onto Air Force P-19, P-23 and other front-line ARFF vehicles. (AN).
