This method defines a test that measures the energy required to rapidly delaminate a sheet-type specimen.
The "Z" directional rupture is initiated by the impact of a pendulum having both a controlled mass and a controlled
velocity that exceeds 6000 times the velocity of tensile strength and other dead-weight testers. The geometry of the
apparatus causes the tensile stress to be rotational in nature with negligible shear stress on the specimen.
The method is suitable for both single and multi-ply paper and paperboard, including coated sheets and
those that are laminated with synthetic polymer films.
