Once the sample shows no visible
signs of water,
use a decanted portion of the sample, maintained
between 1 and 10°C, for the analysis. Note in the report
that the sample has been dried by the addition of a desiccant.
NOTE 9—Suspended water in hazy samples in Groups 1 and 2 can be
removed by the addition of anhydrous sodium sulfate and separating the
liquid sample from the drying agent by decanting without statistically
affecting the results of the test.6
the suspended water can be removed by maintaining the
sample at 0 to 10°C,
