标准摘要
[中文适用范围]： ISO 1924 的这一部分规定了使用以恒定伸长率（20 毫米/分钟）运行的试验机测量纸和纸板的拉伸强度、断裂应变和拉伸能量吸收的方法。 ISO 1924 的这一部分还规定了拉伸指数、拉伸能量吸收指数和弹性模量的计算公式。 符合 ISO 1924 这一部分的测试始终包括拉伸强度的测量。 其他性能的计量或计算由当事人协商一致。 ISO 1924 的这一部分适用于所有纸张和纸板，包括具有高断裂应变的纸张（如果结果在测试机的能力范围内）。 它也适用于瓦楞纸板的组件，但不适用于瓦楞纸板本身。 ISO 1924 的本部分不适用于 ISO 12625-4[2] 适用的薄纸和薄纸产品。 对于实验室板材拉伸性能的测定，建议使用 ISO 5270[3]。 [外文原描述]： ISO 1924-2:2008 specifies a method for measuring the tensile strength, strain at break and tensile energy absorption of paper and board, using a testing machine operating at a constant rate of elongation (20 mm/min). ISO 1924-2:2008 also specifies equations for calculating the tensile index, the tensile energy absorption index and the modulus of elasticity. Testing in conformance with ISO 1924-2:2008 always includes the measurement of tensile strength. Measurement or calculation of other properties is subject to agreement between the parties concerned. ISO 1924-2:2008 is applicable to all papers and boards, including papers with a high strain at break if the results are within the capacity of the testing machine. It also applies to the components of corrugated board but not, however, to corrugated board itself.
