ASTM WK44964

    Revision of D4483 - 05a(2011) Standard Practice for Evaluating Precision for Test Method Standards in the Rubber and Carbon Black Manufacturing Industries

    (What is a Work Item?)

    Active Standard: D4483 - 14a

    Developed by Subcommittee: D11.16 | Committee D11 | Contact Staff Manager



    WK44964

    1. Rationale

    When the ballot to add paragraph 7.2.1 was being prepared, the text copied from an older version of D4483 inadvertently included a sentence that should have been omitted. Alan Veith voted negative on the ballot because of the included sentence. Alan agreed that the paragraph was needed and volunteered to withdraw his negative so this could proceed to publication with the paragraph on the condition that another ballot be submitted to remove the erroneous sentence. The chairman of D11.16 agrees that the sentence should be removed.
