5.1?This test method is used as an indication of free water and sediment suspended as haze, cloudiness, or droplets in middle distillate fuels such as Grades No. 1 and 2 fuel oil (Specification D396), Grades No. 1-D and 2-D diesel fuel (Specification D975), and Grades No. 0-GT, 1-GT, and 2-GT gas turbine fuels (Specification D2880), similar fuels and blendstocks used to make these fuels. 5.2?Appreciable amounts of free water and sediment in a fuel oil tend to cause fouling of fuel-handling facilities and to give trouble in the fuel system of a burner or engine. An accumulation of sediment in storage tanks and on filter screens can obstruct the flow of oil from the tank to the combustor. Free water in middle distillate fuels can cause corrosion of tanks and equipment, and if detergent is present, the water can cause emulsions or a hazy appearance. Free water can support microbiological growth at fuel-water interfaces in fuel systems. 1.1?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.
1.2?The values stated in SI units are to be regarded as standard. 1.2.1?ExceptionThe non-SI values are for information only. 1.3?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
