KN-1384 Corrosion Test for Engine Coolants
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 testsRead

KN-4340 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
occurRead

KN-665 Rusting Characteristics of Oils
In many instances, such as in the gears of a steam turbine, water can become mixed with the lubricant, and rusting of ferrous parts can occur. This test indicates how well inhibited mineral oils aid in preventing this type of rusting. This test method is also used for testing hydraulic and circulating oils, including heavier-than-water fluids. It is used for specification of new oils and monitoring of in-service oilsRead
