Consists of two heat-transfer corrosion cells with temperature and pressure controls for evaluating engine coolant samples in accordance with ASTM D4340. Maintains aluminum alloy specimens at constant temperature in the presence of 500 mL samples. Each corrosion cell includes a borosilicate glass test cell, heat transfer bar, aluminum test specimen with thermocouple port, Type J thermocouple, 950W band heater, pressure gauge, pressure relief valve, stainless steel end plates with support rods, fill plug and o-rings, and acrylic safety shields. Digital temperature controllers maintain specimens at temperatures of up to 210 ± 1°C throughout the test period. Test cells are mounted on a finished steel base. Controls are housed in a separate finished steel cabinet.
Provides a laboratory screening procedure for evaluating the corrosion preventing capabilities of engine coolants under heat transfer conditions that may be encountered in aluminum cylinder head engines. Corrosion preventing effectiveness is determined by the change in weight of an aluminum alloy test specimen after an extended period at elevated temperature in the presence of a coolant sample.
