    ASTM D1122

    Significance and Use

    4.1 The relative density of an engine coolant may be used to determine the approximate percent glycol, freezing point, and boiling point, provided the glycol type is known.

    4.2 The relative density of an engine coolant concentrate can be used as a production control test.

    1. Scope

    1.1 This test method covers the determination of the relative density of engine coolant concentrates and engine coolants.

    1.2 The values stated in SI units are to be regarded as 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.
