The mass of particulates present in a fuel is a significant factor, along with the size and nature of the individual particles, in the rapidity with which fuel system filters and other small orifices in fuel systems can become plugged. This test method provides a means of assessing the mass of particulates present in a fuel sample.
The test method can be used in specifications and purchase documents as a means of controlling particulate contamination levels in the fuels purchased.View Less
1.1 This test method covers the determination of the mass of particulate contamination in B100 biodiesel in accordance with Specification D 6751 and BXX blends that are prepared against all No. 1 and No. 2 grade fuels allowed within Specifications D 396, D 975, D 2880, and D 3699.
Note 1-Middle distillate fuels with flash points less than 38°C have been ignited by discharges of static electricity when the fuels have been filtered through inadequately bonded or grounded glass fiber filter systems. See Guide D 4865 for a more detailed discussion of static electricity formation and discharge.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses 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 and health practices and determine the applicability of regulatory limitations prior to use.
