(Practice)Standard Practice for Testing Engine Coolants in Car and Light Truck Service
Standard Practice for Testing Engine Coolants in Car and Light Truck Service
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. light and heavy duty truck service (according to the test vehicles 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 and heavy duty 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, D6210, D7517, D7518, 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 7.

4.1 Test coolant shall be a new coolant. The coolant is tested at the recommended concentration in an aqueous solution made
with water that complies with the water recommendation published in Specifications D3306 and D6210. A minimum of five test
vehicles per coolant are required, ten are recommended, but this number may be adjusted by agreement between customer and
supplier. The test vehicles shall have been in service less than 3 months, 3000 miles, 5000 km, or 500 operating hours. Alternate
specific requirements may always be agreed between customer and supplier. Customer and supplier may also choose to follow
