ASTM  D1122 Density or Relative Density of Engine Coolant Concentrates and Engine Coolants by the Hydrometer

In coolants, density may give an indication of glycol content.  This test determines density or relative density (specific gravity) of a coolant using a hydrometer.  This test is also used as a quality control tool and to determine specification adherence.

 The sample is temperature controlled in a hydrometer cylinder.  The proper hydrometer (a sealed long tube with a weight at the bottom used to measure buoyancy) is inserted and given time to equilibrate.  The value is read off the hydrometer and the value of interest is calculated and reported.
