GB/T 19466.6-2009/ISO 11357-3:1999 Part 6 Oxidation induction period Determination of oxidation induction time (isothermal OIT) and oxidation induction temperature (dynamic OIT).

Differential thermal analyzer is an instrument that measures the temperature difference and temperature relationship between a substance and a reference substance. In the DTA test, the temperature change of the sample is caused by the endothermic or exothermic effect of phase transition or reaction.
