Comments were received on previous ballots that offered suggestions on clarifying Figure A1.1 on the Upper Hemispherical Testing Head. The task group agreed with most of the suggested changes to the drawing. This ballot item updates Fig. A1.1 with these changes as well as with some additional changes proposed by the task group. In addition to the changes to Fig. A1.1, several minor changes are being made to section A1.1 to clarify its meaning and to make it consistent with the new figure.
