GB/T 22896-2008 "Paper and board - Determination of curl - Single vertically suspended test piece method" specifies a method for determining the curl of paper and board using a single vertically suspended test piece. It is applicable to test pieces with a curl shape approximating an arc and exhibiting stable curvature. The test piece is suspended vertically, and the chord length and the distance from the chord to the arc are measured to calculate the degree of curl. The standard defines the suspension method, measurement tools, and environmental conditions, making it suitable for evaluating curl in settings such as laboratories or printing workshops.
