ASTM D2709 for water and sediment in middle distillate fuels by centrifuge
1. Scope
1.1 This test method covers the determination of the volume of free water and sediment in middle distillate fuels having viscosities at 40°C (104°F) in the range of 1.0 to 4.1 mm2/s (1.0 to 4.1 cSt) and densities in the range of 770 to 900 kg/m3.
NOTE 1 - Fuels corresponding to Specification D975 Grades 1D and 2D, Specification D2880 Grades 0-GT, 1-GT and 2-GT, and Specification D3699 Grades 1-K and 2-K will usually fall in this viscosity and density range. Test Method D1796 is intended for higher viscosity fuel oils.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parenthesis are for information only.
1.3 This standard does not purport to address all safety problems, 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 application of regulatory limitations prior to use.
