    New Test Method for Standard Test Method for Enhanced Filter Block Tendency Determination

    (What is a Work Item?)

    Developed by Subcommittee: D02.14 | Committee D02 | Contact Staff Manager



    WK66555

    1. 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 procedure and associated filter type, is applicable to fuels within the viscosity range of 1.3 to 6.0 mm2/s at 40C. The test method is enhanced test method and provide higher resolution which is based on ASTM D2068. NOTE 1ASTM specification fuels falling within the scope of this test method are: Specifications D396 Grades No 1 and 2; Specification D975 Grades 1-D, low sulfur 1-D and 2-D; Specification D2880 Grades 1-GT and 2-GT; Specification D6751. 1.2 This test method is not applicable to fuels that contain free (undissolved) water. 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.


    Keywords

    Automotive diesel; biodiesel; filterability; filter blocking tendency (FBT); gas oil; marine diesel; middle distillates

    Rationale

    the test method method provides better resolution which is primary designed for screening fuel cleanness to prevent filter premature plugging issue and potential fuel system failure due to fuel cleanness. The potential users will be the customers of EMA members, fuel suppliers.
