Results and discussion

Any other information on results incl. tables

No endothermic or exothermic effect of the test substance between 17°C and 81°C (melting temperature of the test substance) was observed. It demonstrated that the test substance is not self-ignitable in the temperature range of 17°C - 81°C.

 

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

Applicant's summary and conclusion

Conclusions:
The self-ignition temperature of the test substance was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device. Based on the results obtained the test substance is considered ‘not self-ignitable’ in the temperature range of 17°C - 81°C.
