A if the purchase order specifies a minus tolerance for wall thickness smaller than the applicable value given in this table,the plus tolerance for wall thickness shall be increased by an amount sufficient to maintain the applicable tolerance range.
B for pipe with D≥355.6mm(14.000 in )and t≥25.0mm(0.984 in),the wall-thickness tolerance locally may exceed the plus tolerance for wall thickness by an additional 0.05t,provided that the plus tolerance for mass is not exceeded.
C the plus tolerance for wall thickness does not apply to the weld area.
