As part of the second phase in development of environmentally compliant solvent alternatives to P-D-680, Navy field demonstrations were initiated at NADEP, Cherry Point, NC, NAWC, Patuxent River, MD, NSWC, Carderock Division, MD, and Naval Station, Mayport, FL. The main objectives of this demonstration were to validate performance of candidate solvents with existing Naval aviation and shipboard equipment, and to determine the environmental applicability for these candidate solvents. Two 2 petroleum based solvents and two 2 terpenehydrocarbon blended solvents have been selected as candidates for these field demonstrations. NADEP evaluated four 4 candidate solvents in various Navy aviation and ground equipment i.e., engine, bearings at five 5 different types of repairmaintenance shops. NAWC evaluated a candidate solvent using IT-30 parts washer and aircraft support equipment i.e., compressor valves, pistons, bearings, etc.. In the shipboard bearing cleaning applications, NSWC evaluated an odorless candidate solvent using an existing parts washer. Also, Naval station, Mayport evaluated an odorless candidate solvent in Navy missile cleaning applications. Field test results showed that both severe hydrotreated odorless hydrocarbon solvents and hydrotreated terpenehydrocarbon blended solvents were well accepted in all applications. All candidate solvents tested were rated by users as acceptable replacements for F-D-680.
