ASTM D2847 Standard Practice for Testing Engine Coolants in Car and Light Truck Service
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.
