Description

Significance and Use

This test method is intended for use in the laboratory or field in evaluating distillate fuel cleanliness.

A change in filtration performance after storage, pretreatment, or commingling can be indicative of changes in fuel condition.

Relative filterability of fuels may vary depending on filter porosity and structure and may not always correlate with results from this test method.

Causes of poor filterability in industrial/refinery filters include fuel degradation products, contaminants picked up during storage or transfer, incompatibility of commingled fuels, or interaction of the fuel with the filter media. Any of these could correlate with orifice or filter system plugging, or both.

1. Scope

1.1 This test method covers a procedure for determining the filterability of distillate fuel oils within the viscosity range from 1.70 to 6.20 mm ² /s (cSt) at 40°C.

Note 1

ASTM specification fuels falling within the scope of this test method are Specification D 396 Grade Nos. 1 and 2, Specification D 975 Grades 1-D, low sulfur 1-D, 2-D, and low sulfur 2-D, and Specification D 2880 Grade Nos. 1-GT and 2-GT.

1.2 This test method is not applicable to fuels that contain undissolved water.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses 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.
