Paper and board -- Determination of bending stiffness -- Resonance method
This standard has been revised by ISO 5629:2017
Applies to a wide range of papers and boards, but for some materials, such as multi-ply papers and boards, papers and boards with appreciable curl, some soft papers with grammage below about 40 g/m , the measured numerical value may not be strictly identical with the bending stiffness. It does not apply to corrugated boards.
