    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to conclude the previous ballot process and proceed to publication of D4417-19, several comments and negatives were withdrawn with the understanding that they would be taken up at the February committee meeting.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 modifications to section 5.1 are in response to two concerns by committee members. - Now that portable stylus roughness instruments are included in the standard, it may not be appropriate to state that all instruments are readily portable and sufficiently sturdy for use in the field - A concern was raised that Note 2 could be interpreted to suggest that Methods C and D were superior to the other methods.
