ASTM WK68650

    Revision of D2414 - 18a Standard Test Method for Carbon Black—Oil Absorption Number (OAN)

    (What is a Work Item?)

    Active Standard: D2414 - 18a

    Developed by Subcommittee: D24.11 | Committee D24 | Contact Staff Manager



    WK68650


    Keywords

    carbon black; epoxidized fatty-acid ester (EFA); n–dibutyl phthalate; oil absorption number; paraffin oil;;

    Rationale

    For the OAN method, the new SRB9 reference materials have a narrower range than the SRB8 set because some of the grades used to develop the SRB8 set were no longer available. Therefore, prohibition of not mixing SRB sets needs to be removed to allow using a SRB-8C along with SRB9 materials to extend the normalization range where required. See Ballot Item for D4821 for more clarification.
