Applicant's summary and conclusion

Conclusions:

No exothermic effects with an overall energy above 500 J/g were found up to a final temperature of 500°C. Therefore the main test on explosive properties was not necessary. Based on the DSC measurement the test item has no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14..

Executive summary:

The explosive properties of acylglycinate GCK-11 -T were investigated via thermal stability measurements. In this screening test, endothermic and exothermic effects in the range from ca. 20°C up to 500°C were measured via DSC. An exothermal effect was observed in the temperature range of 180 -235°C and multiple exothermic effects in the temperature range of 295 -440°C with an overall energy of 181 J/g. As no exothermic effects with an overall energy above 500 J/g were found up to the final temperature of 500°C, the main test on explosive properties according to EU Method A.14 (Explosive properties) and EPA OPPTS 830.6316 (Explodability) was not necessary. Based on the DSC measurement the test item has no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14..
