Standard Test Method for Engine Coolant Corrosion Protection Under Accelerated Thermal and Oxidizing Conditions Using a Rotating Pressure Vessel

Importancia y uso:

4.1 Engines operating under severe conditions involving high temperatures, hot spot areas, entrained air, or small cooling systems, or combinations thereof, are placing greater emphasis on engine coolant oxidation stability and corrosion protection. This test method provides an accelerated test method to assess engine coolant performance under high temperature oxidizing test conditions of new, used, or recycled engine coolants, or combinations thereof. The test method may also serve as a screening tool to determine oxidation stability. The test results of this method cannot stand alone as evidence of satisfactory oxidation stability and corrosion protection. The actual service of an engine coolant formulation can be determined only by more comprehensive bench, dynamometer, and field tests.
