Standard Test Method for Water and Sediment in Middle Distillate Fuels by Centrifuge
 N D2709

Annotation

This test method covers the determination of the volume of free water and sediment (as a percentage of the sample) that is suspended in the bulk fuel in middle distillate fuels with viscosities in the range of 1.0 mm2/s to 4.1 mm2/s at 40 °C (1.0 cSt to 4.1 cSt at 104 °F) and densities in the range of 770 kg ?m3 to 900 kg ?m3 at 15 °C.

NOTE 1—Fuels corresponding to Specification D396 Grades No. 1 and 2, D975 Grades No. 1-D and 2-D, Specification D2880 Grades No. 0-GT, 1-GT and 2-GT, and Specification D3699 Grades No. 1-K and 2-K and similar middle distillate fuels and blendstocks will usually fall in this viscosity and density range. Test Method D1796 is intended for higher viscosity fuel oils.

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

Exception—The non-SI values are for information only.

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.
