Results and discussion

Results:
UM-235 is not a self-heating substance.

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 consistency of the sample was unchanged, i.e. no reaction and/or decomposition of the test substance was observed.
