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to conclude the previous ballot process and proceed to publication of D4417-19, several comments and negatives were withdrawn with the understanding that they would be taken up at the February committee meeting.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. Section 10.2.1 currently indicates that comparison can be done by touch. A committee member pointed out that touching the blasted surface with a bare finger could contaminate the surface. This modification attempts to address that concern.
