Also termed as OIT equipment is designed to check the oxidation induction time of polymers. The referred ASTM standard recommend two procedures to determine Oxidation induction time test. One is Differential Scanning Calorimeter (DSC) method & second is Differential thermal Analysis (DTA) method.
International Equipments offer Oxidation Induction test apparatus based on Differential Thermal Analysis (DTA) principle. Tests carried out with both DTA or DSC methods are similar comprising of two pans inside a thermal equilibrium zone with one reference “Empty Pan” and Second “Specimen Pan”. “Oxidation Induction Time” the term itself specifys its meaning. Time required for a polymeric material to oxidise (degrade) when induced (“subjected to” or “reacted”) with oxygen. Oxygen being a highly penetrating gas even polymers tend to oxidise or degrade when exposed to oxygen. Oxidation is an exothermic reaction (reaction where polymer starts throwing heat out of it before it completely degrades or oxidises. This test confirms the sustainability of any polymeric material when subjected to oxygen. Time taken for a material to degrade under specified condition of temperature (200 degree Centigrade) and certain level (80 Cubic.Centimeter) of Oxygen.
This “Oxidation Induction Time Test” test requires only 8 to 10 mg of polymer mixed
with antioxidants and is a very sensitive test. This test being conducted under very stringent conditions of Oxygen and Nitrogen, it is recommended to test this equipment for temperature calibration with metals like “INDIUM” having fixed melting point of 156.6 degree centigrade under inert atmosphere of Nitrogen. The same provision is offered by us in the working and construction of this equipment and its software.
