no self ignition observed under the test conditions

Any other information on results incl. tables

Preliminary test according to EC A.16

An exothermic effect of the test item was observed. The temperature of the test item reached 400°C at an oven temperature of 383°C. It demonstrated that the self-ignition temperature of the test item is 383°C. After the experiment, the test item had turned into a black, expanded residue and was collected in a container that was placed below the cube. It indicated that the test item had decomposed and/or reacted during the experiment. As the preliminary test was positive a main study according to UN N.4 was performed.

Main study according to UN N.4

A negative result was obtained. 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 reaction and/or decomposition of the test item was observed.

Applicant's summary and conclusion

Conclusions:
Self-heating of JNJ-1782820-AAC (T001492) 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
JNJ-1782820-AAC (T001492) is not a self-heating substance.
