Results and discussion

Small-scale preliminary tests
Key result
Parameter:
other: To screen a sample of DEA Borate in order to determine the onset temperature and magnitude of any endothermic or exothermic events when ramped to elevated temperatures. Reported in J.g-1 units.
Value:
383.09
Remarks on result:
other:
Remarks:
The combined value of the two exotherms is less than 500 J.g-1. Therefore the full testing for explosivity is not required.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The total heat of decomposition is 383.09 J.g-1. The combined value of the two exotherms is less than 500 J.g-1. Therefore the full testing for explosivity is not required.
Executive summary:

A Differential Scanning Calorimetry (DSC) test was run according to EC Method A.14 Explosive Properties of Commission Regulation (EC) No 440/2008 of 30 May 2008 and recomended by Transport of Dangerous Goods, Manual of Tests and Criteria, 6th revised edition, UN (New York and Geneva), 2009, ISBN 978-92-1-139155-8 on a sample of DEA Borate in order to determine the onset temperature and magnitude of any endothermic or exothermic events when ramped to elevated temperatures. The total heat of decomposition is 383.09 J.g-1. The combined value of the two exotherms is less than 500 J.g-1. Therefore the full testing for explosivity is not required.
