Results and discussion

Self-heating substances / mixtures
Key result
Test procedure:
100 mm sample cube at 140°C
Result:
negative outcome (no effect observed)

Any other information on results incl. tables

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

After the experiment, the consistency of the sample was unchanged, i.e. no melting or reaction and/or decomposition of the test item was observed.
