Results and discussion

Relative self-ignition temperature (solids)
Key result
Remarks on result:
other: The sample temperature did not reach 400°C by self-heating.

Any other information on results incl. tables

A broad exothermic effect of the test item by self-heating was observed at an oven temperature of 308°C. During this effect, four maximum temperatures were observed. The

highest temperature the test item reached was 399°C.

After the experiment, the test item had turned into a black charred residue and was collected in a container that was placed below the cube. It indicated that the test item had been decomposed and/or reacted during the experiment.

Applicant's summary and conclusion

Conclusions:
No self-ignition of the substance up to 400°C.
Executive summary:

In a GLP study performed according to EC A.16, The self-ignition temperature of X-19924 was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device. The sample temperature did not reach 400°C by self-heating. The substance is considered ‘not self-ignitable’.
