标准摘要
[中文适用范围]： 该文件规定了使用尺寸排阻色谱法（SEC）测定聚合物的平均分子量和分子量分布的方法。 使用通用校准曲线代替传统校准曲线计算平均分子量和分子量分布。 注：本测试方法属于ISO 16014-1中描述的相对方法，但该方法计算的平均分子量和分子量分布等于或接近等于绝对值。 详情见附件A。 [外文原描述]： This document specifies a method for determining the average molecular weight and the molecular weight distribution of polymers using size-exclusion chromatography (SEC). The average molecular weight and the molecular weight distribution are calculated using a universal calibration curve instead of the conventional calibration curve. NOTE This test method is classified as a relative method as described in ISO 16014-1, but the average molecular weights and molecular weight distributions calculated by the method are equal to, or nearly equal to, the absolute values. For details, see the Annex A.
