标准摘要
[中文适用范围]： ISO 11093的本部分规定了通过三点法测定满足以下标准的圆柱形纸芯和纸板芯的弯曲模量的方法： ——内径：50mm至350mm； ——最小壁厚：0.05×内径，但不小于10.0毫米； ——芯线最小长度：10×内径，但不小于1000mm。 如果必须使用弯曲模量来计算纸芯的固有频率，则适用 ISO 11093-8[2] 而不是本国际标准。 [外文原描述]： ISO 11093-7:2011 specifies a method for the determination, by the three-point method , of the flexural modulus of cylindrical paper and board cores, which meet the following criteria: internal diameter: 50 mm to 350 mm; minimum wall thickness: 0,05 × internal diameter, but not less than 10,0 mm; minimum length of core: 10 × internal diameter, but not less than 1 000 mm.
