(Test Method)Standard Test Method for Engine Coolant Corrosion Protection Under Accelerated Thermal and Oxidizing Conditions Using a Rotating Pressure Vessel
Standard Test Method for Engine Coolant Corrosion Protection Under Accelerated Thermal and Oxidizing Conditions Using a Rotating Pressure Vessel
SIGNIFICANCE AND USE
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.
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 after SI units are provided for information only and are not considered standard.
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, health, and environmental 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.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Summary of Test Method
3.1 The engine coolant test fluid and a metal coupon bundle are placed in a covered glassware container in a pressure vessel
equipped with a pressure gauge. The pressure vessel is charged with air or oxygen to a gagegauge pressure of 620 kPa (90 psi,
6.2 bar) (see conversion factor 1), placed in a constant–temperature oil bath set at a controlled temperature (typically 115°C
(239°F) or 150°C (302°F))115 °C (239 °F) or 150 °C (302 °F)) and rotated axially at 100 rpm at an angle of 30° from horizontal
for 168 h. The use of air or oxygen and test temperature is left to the discretion of the user of the test. Engine coolant performance
is assessed for corrosion protection based on changes in metal coupon weights and coolant stability is evaluated based on changes
in coolant physical and compositional properties. The test method is based on a combination of ASTM Test Method D1384
(modified metal coupon bundle) and ASTM Test Method D2272 (glassware, pressure vessel, and bath apparatus) test procedures.
