ASTM WK43225

    Revision of D975 - 13 Standard Specification for Diesel Fuel Oils

    (What is a Work Item?)

    Active Standard: D975 - 14a

    Developed by Subcommittee: D02.E0 | Committee D02 | Contact Staff Manager


    1. Rationale

    Engine requirements for fuel properties have changed and will continue to change in response to demands for lower engine exhaust emission levels, lower fuel consumption, improved performance, and improved reliability. Fuel injection system pressures have increased dramatically resulting in significantly less internal clearance between moving parts. Fuel injectors are required to inject fuel multiple times per combustion cycle with extreme precision for injection starting time, injection volume, and injection ending time. Engine manufacturers and their respective vehicle or equipment customers have implemented fuel filtration changes and improved water separators in an effort to protect the injection system components and provide consistent and reliable performance. Note: This is a replacement for WK31630 that was utilized to develop proposed changes to D975 balloted to Subcommittee E on Ballot D02 E0 (13-02) Item #1. The WK31630 work item and related Collaboration Area have been lost and are not recoverable.
