ISO 11556:2005 gives a procedure for determining the curl of paper and board using a vertically suspended test piece, and defines the terms used in curl measurement.
Abstract
Overview - ISO 11556:2005 (Paper and board - Determination of curl)
ISO 11556:2005 specifies a reproducible procedure for the using a single vertically suspended test piece. The standard defines key terms (curl magnitude, angle of curl axis, concave side), describes sampling and conditioning, prescribes test-piece sizes, required apparatus, measurement accuracy and the calculation of curl as the reciprocal radius of curvature (K, in m⁻¹). It is intended for cases where the curl approximates a circular arc and is stable during cutting and measurement.
