ASTM D1177 Test Method for Freezing Point of Aqueous Engine Coolants
1. Scope
1.1 This test method covers the determination of the freezing point of an aqueous engine coolant solution in the laboratory.
NOTE 1 - Where solutions of specific concentrations are to be tested, they shall be prepared from representative samples as directed in Test Methods D1176. Secondary phases separating on dilution need not be separated.
NOTE 2 - These products may also be marketed in a ready-to-use form (prediluted).
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 and health practices and determine the applicability of regulatory limitations prior to use.
