    Active Standard: B618 / B618M - 14

    Developed by Subcommittee: B07.01 | Committee B07 | Contact Staff Manager



    WK17587

    1. Rationale

    A concern regarding the analysis of the chemical composition and the use of E88 as a reference was discussed at the Nov 2007 committee meeting. This work item is opened to address the concensus of the committee meeting with a revision that eliminates E88 as a reference and emphasizes sampling during pouring as the preferred method to validate conformation of the chemical composition limits.
