D15.10 - Dynamometer and Road Tests

SIGNIFICANCE AND USE
5.1 The data obtained from the use of this practice will provide a basis for the evaluation of coolant performance in passenger car, and light-duty truck service (according to the test chosen). The data obtained may also be used to provide added significance to the data obtained from simulated service and engine dynamometer tests.
SCOPE
1.1 This practice covers an updated procedure for evaluating corrosion protection and performance of an engine coolant in passenger car, light truck service that closely imitates current vehicle and engine manufacturers’ practices.  
Note 1: Coolant evaluation in vehicle service may require considerable time and expense; therefore, the product should be pretested in the laboratory for general acceptability. Typical tests vary from small, closely controlled tests, to large tests where close control is not always practical. The most often referenced protocols for laboratory testing are defined in Specifications D3306, D7714, and D7715.  
1.2 The units quoted in this practice are to be regarded as standard. The values given in parentheses are approximate equivalents 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 precautionary statements are given in Section 7.  
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.

SIGNIFICANCE AND USE
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.
