    ASTM D2570 Simulated Service Corrosion Tester

    KN-2570 Simulated Service Corrosion Tester conforms to ASTM D2570 Standard Test Method for Simulated Service Corrosion Testing of Engine Coolants. An engine coolant is circulated for 1064h at 88℃ (190℉) in a flow loop consisting of a metal reservoir, an automotive coolant pump, an automotive radiator, and the connecting rubber hoses. Test specimens representative of engine cooling system metals are mounted inside the reservoir, which simulates an engine cylinder block. At the end of the test period, the corrosion-inhibiting properties of the coolant are determined by measuring the mass losses of the test specimens and by visual examination of the interior surfaces of the components.
