Scope

1.1 This test method covers the determination of the freezing point of an aqueous engine coolant solution.

1.2 This test method is designed to cover ethylene glycol base coolants up to a maximum concentration of 60 % (v/v) in water; however, the ASTM interlaboratory study mentioned in has only demonstrated the test method with samples having a concentration range of 40 to 60 % (v/v) water.

Note 1--Where solutions of specific concentrations are to be tested, they shall be prepared from representative samples as directed in Test Method D1176. Secondary phases separating on dilution need not be separated.

Note 2

The products may also be marketed in a ready-to-use form (prediluted).

1.3 The values stated in SI units are to be regarded as the standard. The values given in parenthesis are for information only.

1.4 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.
