Standard Test Method for Relative Density of Engine Coolant Concentrates and Engine Coolants By The Hydrometer

Importancia y uso:

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.

4.3 ASTM specifications normally state the temperatures for relative density of fluids; 25 °C, 20 °C, and 15.6 °C are commonly used temperatures.
