Standard Test Method for Free Water and Particulate Contamination in Middle Distillate Fuels (Clear and Bright Numerical Rating)

Importancia y uso:

5.1 The test provides a field test to evaluate visually a fuel sample for particulate matter and free water similar to Test Method D4176 plus a numerical rating for free water. High numerical ratings indicate that the fuel is relatively free of free water. The degree of water and particulate contamination can be measured using other methods such as Test Methods D2276, D2709, and D6304.

Note 2: Clean and bright is sometimes used in place of clear and bright. The meaning is identical.

5.2 The color of the sample does not affect the measurement. Limited laboratory evaluations of samples have determined the degree of free water can be rated in fuels with dark opaque color having a darker rating than five in Test Method D1500.
