Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
yes
Remarks:
The heating rate of the oven over the complete heating range was 0.58 K/min. instead of 0.5 K/min. This was considered uncritical as no self-heating over 400 °C could be observed up to 300 °C.
GLP compliance:
yes (incl. QA statement)

Applicant's summary and conclusion

Conclusions:
The auto-flammability behaviour was determined by placing the test item into a stainless steel cube and heating to an oven temperature from room temperature to 300°C. No increase in the temperature of the sample in comparison to that of the oven could be detected, also no signs of ignition could be observed. Therefore, the test item Addukt TI 65 - MXDA should be considered as not auto-flammable up to the melting point of 265.5 °C – 279.5 °C under the test conditions.
