The meeting was opened at 1:04 p.m. D. Aikens thanked the group for giving up their Sunday afternoons to work on the draft.

H. Pollicove moved that the draft minutes of the May 6, 2001 meeting be approved as amended by G. Kohlenberg. W. Royall seconded the minutes; the motion carried.

The first order of business was to draft an agenda for the two sessions of this meeting.

Agenda for meeting

  1. Introductions - what are you looking for by participating

  2. Report from Switzerland

  3. Report on Northrop's work on calibrating illumination

  4. Timeline and task leaders for metrological-based standard

  5. Objectives for the next meeting

  6. Finish the first draft of BSR/OEOSC OP1.002 for publication

  7. Initiative for standard illumination hardware

  8. Line-by-line review of BSR/OEOSC OP1.002

J. Hamilton moved that the Task Force accept the agenda proposed by D. Aikens. B. Netherton seconded the motion. The motion carried.

Introductions

D. Aikens asked for a round of introductions. Each person stated his/her interest in this standard.

Report from Switzerland

H. Pollicove discussed the activities during the ISO/TC 172/SC 1 meeting in St. Gallen, Switzerland. Scratch and dig issues were not covered at that time.

Report on Northrop's work on calibrating illumination

J. Hamilton reviewed his efforts in examining the illumination conditions for evaluating scratches. There is not a lot of correlation among the several methods of viewing samples. Northrop has a limited list of samples that it using in this evaluation. He asked others at the meeting to consider submitting samples relevant to their business to be included in this test.

There followed a general discussion concerning the merits of an appearance imperfection standard and a performance imperfection standard. D. Aikens finally reminded the group that the group was revisiting the same issues that were discussed in the previous meeting.

The group recessed at 2:36 p.m. and reconvened at 2:54 p.m.
