标准范围
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.
