    Rationale

    In an effort to conclude the previous ballot process and proceed to publication of D4417-19, several comments and negatives were withdrawn with the understanding that they would be taken up at the February committee meeting. This series of ballots reflects those suggestions, as agreed upon by all in attendance at the February D01.46 committee meeting. These changes concern a sentence in section 4.1.1 that suggests Method A does not apply for combinations of blast meda. However, during the last round of ballotting it was observed that comparators do exist for some combinations of blast media, and the members present at the February committee meeting agreed that the last sentence of that section should be removed.
