ASTM-D7820 › Standard Test Method for Engine Coolant Corrosion Protection Under Accelerated Thermal and Oxidizing Conditions Using a Rotating Pressure Vessel
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers determination of engine coolant corrosion protection and stability under accelerated thermal and oxidizing conditions using a rotary pressure vessel.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in 6.2, 6.3, 6.4, 6.5, 6.7, 6.8, 6.9, 6.10, 11.1, 12.8, 12.9, and 12.10.
Significance and Use
4.1 Engines operating under severe conditions involving high temperatures, hot spot areas, entrained air, and/or small cooling systems are placing greater emphasis on engine coolant oxidation stability and corrosion protection. This standard provides an accelerated test method to assess engine coolant performance under high temperature oxidizing test conditions of new, used, and/or recycled engine coolants. 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.
