Significance and Use
4.1 This test method provides a laboratory technique capable of reproducing the complex environmental stresses a coolant encounters under actual engine operating conditions. The test method provides improved discrimination over glassware and simulated service tests and improved correlation with field service. Although the test method is particularly valuable for developing coolants for increased service requirements, it remains that field testing is necessary to evaluate coolant performance completely.
Scope
1.1 This test method covers a full-scale clean engine test designed to evaluate corrosion protection and inhibitor stability of engine coolants under simulated heavy-duty driving conditions.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 6.
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.
