Standard Test Method for Temperature and Hard Water Stability of Engine Coolants
N D7437
Annotation
This test method covers a simple glassware-type procedure for evaluating the effects of temperature and hard water on the stability of engine coolants at elevated temperatures under controlled laboratory conditions.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
