Description

ASTM D2068-08

Historical Standard: Standard Test Method for Determining Filter Blocking Tendency

ASTM D2068

Scope

1.1 This test method covers three procedures for the determination of the filter blocking tendency (FBT) and filterability of middle distillate fuel oils and liquid fuels such as biodiesel and biodiesel blends. The 3 procedures and associated filter types, are applicable to fuels within the viscosity range of 1.3 to 6.0 mm²/s at 40C.

Note 1

ASTM specification fuels falling within the scope of this test method are: Specifications D 396 Grades No 1 and 2; Specification D 975 Grades 1-D, low sulfur 1-D and 2-D; Specification D 2880 Grades 1-GT and 2-GT; Specification D 6751.

1.2 This test method is not applicable to fuels that contain free (undissolved) water (see ).

1.3 The values stated in SI Units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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.
