Warp:  Any distortion in the plane of the door itself, and does not refer to the door in relation to the frame or the jamb in which it is hung.  Warp will be measured in two different planes of each door considering the combined warp in any two terms (A, B and C below).  The term warp includes bow, cup and twist, which are defined as follows:

A. Bow:  Flatwise deviation from straight line drawn from top to bottom;  curvature along length of door.

B. Cup:  Deviation from straight line drawn from side to side;  curvature along width of door.

C. Twist:  Deviation in which one or two corners of door are out of plane with other corners of door.
