ISO 11357-6:2002
Plastics — Differential scanning calorimetry (DSC) — Part 6: Determination of oxidation induction time
This part of ISO 11357 specifies a method for the determination of the oxidation-induction time (OIT) of polymeric materials by differential scanning calorimetry (DSC). It is applicable to polyolefin resins that are in a fully stabilized/compounded form, either as raw materials or as finished products. It may be applicable to other plastics.
