maximum tensile force per unit width that paper and board will withstand before breaking under the conditions defined in this International Standard
ISO 1924-2:2008(en), 3.1
elongation
increase in length of a test piece
Note 1 to entry: Elongation is expressed in millimetres.
ISO 1924-2:2008(en), 3.3
strain at break
ratio of the measured elongation at the moment of rupture of a test piece of paper, when extended under the conditions defined in the standard method of test, to the initial test length
ISO 1924-2:2008(en), 3.5
tensile energy absorption index
tensile energy absorption divided by the grammage
ISO 1924-2:2008(en), 3.7
tensile index
tensile strength divided by the grammage
ISO 1924-2:2008(en), 3.2
strain
ratio of the elongation of a test piece to the initial test length
Note 1 to entry: Strain is expressed as a percentage of the initial test length.
Note 2 to entry: The initial test length of the test piece is the same as the initial span between the clamping lines.
ISO 1924-2:2008(en), 3.4
tensile energy absorption
amount of energy per unit surface area of a test piece when it is strained to the maximum tensile force
Note 1 to entry: Surface area is calculated as test length multiplied by width.
ISO 1924-2:2008(en), 3.6
modulus of elasticity
maximum slope of the force-elongation curve multiplied by the initial length divided by the width and the thickness of the test piece
