Results and discussion

Any other information on results incl. tables

A negative result was obtained. No spontaneous ignition occurred and no exothermic effect of the test substance was observed. It demonstrated that the test substance is “not a self-heating substance”. According to the UN guideline, no further testing is required.

 

After the experiment, the test substance had turned into a purple grey residue. It indicated that the test substance had decomposed and/or reacted during the experiment.

Applicant's summary and conclusion

Conclusions:
Self-heating of V173520 was determined in accordance with UN Test N.4 “Test Method for Self-heating Substances”.

From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that V173520 is not a self-heating substance.
