ASTM WK45533

    Revision of D6751 - 12 Standard Specification for Biodiesel Fuel Blend Stock (B100) for Middle Distillate Fuels

    (What is a Work Item?)

    Active Standard: D6751 - 15a

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


    1. Rationale

    This ballot is to include D7668 as an additional test method in the Cetane Number section as a method for measuring DCN which can be compared to the cetane number specification of 47. D613 is maintained as the referee method. A large interlaboratory study was conducted in 2013. In this study D7668 tested 20 samples of both #1 and #2 Diesel, B5 and B20 Biodiesel Blends and Biodiesel. The precision obtained was R=1.2 for a DCN of 47 compared to R=3.7 for D613. No bias was observed for these samples when statistically compared to the same samples tested by D613. The research report RR:D02-1771 supporting the precision statement can be obtained from the technical contact.
