ASTM D1384 Corrosion Test For Engine Coolants In Glassware
this test method will generally distinguish between coolants that are definitely deleterious from the corrosion standpoint and those that are suitable for further evaluation.however, the results of this test method cannot stand alone as evidence of satisfactory corrosion inhibition. the sctual serivice value of an engine coolant formulation can be determined only by more comprehensive bench,hynamometer,and field tests

ASTM D2809 Apparatus for Cavitation Corrosion and Erosion-Corrosion Characteristics
KN-2809 Apparatus for Cavitation Corrosion and Erosion-Corrosion Characteristics conforms to ASTM D2809 Standard Test Method for Cavitation Corrosion and Erosion-Corrosion Characteristics of Aluminum Pumps with Engine Coolants. This test method can be used to distinguish between coolants that contribute to cavitation corrosion and erosion-corrosion of aluminum automotive water pumps and those that do not. It is not intended that a particular rating number, as determined from this test, will be equivalent to a certain number of miles in a vehicle test; however, limited correlation between bench and field service tests has been observed with single-phase coolants. Field tests under severe operating conditions should be conducted as the final test if the actual effect of the coolant on cavitation corrosion and erosion-corrosion is to be appraised. It is also possible, with proper control of the test variables, to determine the effect of pump design, materials of construction, and pump operating conditions on cavitation corrosion and erosion-corrosion damage.

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.

ASTM D1177 Automatic Freezing Point Of Aqueous Engine Coolants
This tester involves the determination of the time-temperature curve prior to freezing and the determination of the horizontal or flattened portion of the freezing curve. The freezing point is taken as the intersection of projections of the cooling curve and the freezing curve. If the solution supercools, the freezing point is the maximum temperature reached after super cooling

ASTM D4340 Corrosion Of Cast Aluminum Alloys In Engine Coolants
It is essential that engine coolants prevent heat-transfer corrosion of aluminum cylinder heads during engine operation. Any corrosion products formed may deposit on interior radiator surfaces, reducing heat-transfer efficiency of the radiator. Overheating and boil-over of the cooling system may then occur
