[Basic Technical Indicators]:
Temperature range: Room temperature -1150 ℃
Heating rate: 0.1 ℃/min to 80 ℃/min
Temperature accuracy: ± 0.1 ℃
DTA resolution: 0.01 μ v

[Overview]
The oxidation induction period thermal stability test is applicable to the national standard GB/T17391-1998
Main parameters：
Differential Thermal Analysis (DTA), Differential Scanning Calorimetry (DSC), or other similar thermal analysis instruments that can continuously record the temperature of the sample,
Temperature control accuracy of 0.1 degrees
Test method:
1. Take a small amount of sample and place it in the instrument sample holder, then connect it to oxygen and nitrogen. Raise the temperature from room temperature to 200 ℃± 0.1 ℃ at a rate of 20 ℃/min under nitrogen and maintain a constant temperature for 7 minutes;
2. After maintaining a constant temperature of 200 ℃ for 7 minutes, quickly switch to oxygen and record the time when the curve changes significantly, which is the oxidation induction period time.
[Other uses]
Measure physical and chemical changes related to heat, such as the melting point, melting heat, crystallization and crystallization heat, phase transition reaction heat, thermal stability, and other changes of a substance.
