the cull area. Under B enter the breadth of the cull area. As used in this context, 

 width and breadth mean the long and short measurements of the cull area. Under S 

 indicate the shape of figure most closely approximating the cull area. For an ellipse 

 (including a circle) enter E. For a rectangle (including a square) enter R. For 

 ring-shaped defect, the outer and inner dimensions of the ring are recorded under W 

 and B respectively, and "A" is the shape code (fig. 6). 



Pie-shaped defect affecting an entire segment of the cross section can be recorded 

 by "P" for shape. Then, W/B is the fraction of the circle to be deducted. 



If called for, the procedure outlined for the First Cull Area will be repeated for 

 the Second Cull Area and/or the Third Cull Area. 



More than one rot column can be recorded under First Cull Area if there is at least 

 one intervening measured section with no entry in that column.
