ISO 1924-3:2005规定了使用以恒定伸长率（100 mm/min）运行的试验机测量拉伸强度、断裂应变、拉伸能量吸收和拉伸刚度的方法。ISO 1924-3:2005还规定了拉伸指数、拉伸能量吸收指数、拉伸刚度指数和弹性模量的计算公式。

ISO 1924-3:2005 specifies a method for measuring the tensile strength, strain at break, tensile energy absorption and tensile stiffness, using a testing machine operating with a constant rate of elongation (100 mm/min). ISO 1924-3:2005 also specifies equations for calculating the tensile index, the tensile energy absorption index, the tensile stiffness index and the modulus of elasticity.
