Plastics -- Determination of average molecular mass and molecular mass distribution of polymers using size-exclusion chromatography -- Part 4: High-temperature method
ISO 16014-4:2012 specifies a method for determining the average molecular mass and the molecular mass distribution of polymers by size-exclusion chromatography (SEC) using an organic eluent at temperatures between 60 °C and 180 °C. The average molecular mass and the molecular mass distribution are calculated from a calibration curve prepared using polymer standards. Therefore, this test method is classified as a relative method.
