October 26, 1982 MEMORANDUM FOR: Victor Stello, Jr.
FROM:
Joseph F. Scinto
SUBJECT:
COMMENTS ON MINUTES OF CRGR MEETING NUMBER 21 On page 1 of the Minutes, dated October 20, 1982, I would note that the way in which RTNDT for the screening criterion is to be computed (by including a 2 sigma value to the mean values, p.5-5 of the draft) makes the 270"F screening criterion more protective than figure 8.3 in the draft report might suggest. That figure provides longitudinal crack extension frequencies for mean surface RTNDT, rather than for RTNDT computed as mean plus 2 sigma.
