Results and discussion

Any other information on results incl. tables

No self-ignition temperature was observed up to the temperature of decomposition (determined to 272°C, i.e. 545 K in a separate test, Study No.: 805-102-4823).

An unknown exothermic reaction was detected at about 431 min, however it cannot be considered self-ignition because the temperature of the sample did not reach 400 °C.

  

Applicant's summary and conclusion

Conclusions:
No self-ignition temperature was observed up to the temperature of decomposition (determined to 272°C, i.e. 545 K in a separate test, Study No.: 805-102-4823).
Executive summary:

A certain volume of the test item under the assay was placed in an oven at room temperature; the temperature /time curve was recorded while the temperature of the oven was increased at a rate of 0.5 °C/min. For the purpose of this test, the temperature of the oven at which the sample temperature reaches 400 °C by self-heating is called the self-ignition temperature.

Three replicate tests were performed.

No self-ignition was observed up to the temperature of decomposition (determined to 272°C, i.e. 545 K in Study No.: 805-102-4823).

An unknown exothermic reaction was detected at about 431 min, however it cannot be considered self-ignition because the temperature of the sample did not reach 400 °C.
