Any other information on results incl. tables

After the experiment, major part of the test substance was unchanged but a small part of the test substance had turned into a light brown residue. It indicated that this part had decomposed and/or reacted during the experiment but this decomposition/reaction had not caused an exothermic effect. Based on this, it was concluded that the test substance is “not a self-heating substance”. According to the guideline, no further testing was required.

Applicant's summary and conclusion

Conclusions:
After the experiment, major part of the test substance was unchanged but a small part of the test substance had turned into a light brown residue. It indicated that this part had decomposed and/or reacted during the experiment but this decomposition/reaction had not caused an exothermic effect. Based on these findings it was concluded that the test substance is “not a self-heating substance”.
Executive summary:

The ability of the test substance to undergo oxidative self-heating was determined by Test 1 of the Modified Bowes-Cameron Cage test. The experiment was carried out according to an internationally accepted guideline and under GLP.

The test substance was exposed to air at temperatures of 140°C using a temperature controlled laboratory oven, cubic stainless steel wire sample containers of 100 mm wide, NiCr/Ni thermocouples and a temperature recording device.
