Innovation application: Determination of Oxidation Induction Time for Polymer Materials

Title Determination of Oxidation Induction Time for Polymer Materials
Abstract

Determination of oxidation induction time of polymer materials according to testing method of differential scanning calorimeter as well as international standards:

  • EN 728, Plastics piping and ducting systems. Polyolefin pipes and fittings. Determination of oxidation induction time;
  • EN ISO 11357-6, Plastics. Differential scanning calorimetry (DSC). Part 6: Determination of oxidation induction time (isothermal OIT) and oxidation induction temperature (dynamic OIT).
Keywords Oxidation induction time, polymer materials, quality control.
