Description / Abstract:
This Technical Specification describes a method for determining
the fracture toughness of paper and board using a tensile testing
machine operated with a constant rate of elongation. This Technical
Specification also describes the determination of the fracture
strength and fracture strain of a notched paper web with an
assigned standard web geometry. This information is used to rank
the fracture properties of paper materials.
This Technical Specification is applicable to all kinds of paper
and paperboard, except for certain special grades, such as creped
paper and other paper materials that significantly deviate from
exhibiting monotonically decreasing tangential stiffness during
tensile testing. This Technical Specification does not apply to
corrugated fibreboard.
