    Rationale

    During D02 (20-2) Ballot an affirmative with comments vote was received from an D02.03 member regarding the re-approval of D4927. The comments were found to have technical merit and for the most part perhaps be too technical to be considered editorial. During the D02.03 X-ray subsection virtual meeting held June 15, 2020 a ballot to attempt to address the comments in an overall way was approved.
