Simulated Service Corrosion Testing of Engine Coolants Tester ASTM D2570

In a closed system consisting of a reservoir, a water pump, a radiator and a rubber tube, the sample was circulated for 1064 hours at 88°C and a certain flow rate. The weight loss of the sheet and the visual inspection of the state surface of the inner surface of each component are determined, and the performance change of the sample is determined by analyzing the sample taken from the system periodically during the test cycle.
