Need to understand....

    My Sep 91 copy of 275 states on pg 64 in Table 5-11 that the 
  internal minimum annular ring (MAR) for Class 1, 2 and 3 (have 
  absolutely no idea what Class 3 Military means) shall be .001. My 
  fabricator points out that the Mar 92 copy of 276 states on pg 9 
  para 3.7.2 that the internal MAR for Class 3 shall be .001, fine, 
  but that the MAR for Class 2 allow 25% or 90 degree breakout. Which
  boat did I miss this time????? Also, if someone could explain the 
  REJECT of Concept A, in Fig 1 Coupon F on pg 9 of 276, I would be 
  very grateful. Thanks in advance.
