    Rationale

    The need to make revisions to Test Method D6556-19 has been discussed over the course of the last several meetings of Subcommittee D24.21. This work item will cover a number of ballot items to improve the usability and clarity of this Test Method. The Subcommittee has discussed these specific changes, and determining that the changes are minor, as most are to improve clarity, the Subcommittee feels, and the Committee Chairman agrees, that these changes should be submitted for Concurrent Main/Subcommittee Ballot. The Subcommittee respectfully asks for an affirmative vote on these important revisions.
