(i) is within 25 percent of the sling width of the edge, or

(ii) covers 25 percent of the sling width,

(i) in an area that is within 25 percent of the sling width of the edge, or

(ii) over an area that is more than 12.5 percent of the width of the sling;

(f) weft thread damage allows warp threads to separate over an area that is wider than 25 percent of the sling width and longer than twice the sling width.
