Applicant's summary and conclusion
- Conclusions:
- Based on items 3.1 and 3.3 as outlined below, AES is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed.
The result of item 3.2 (oxygen balance) is not considered relevant for this substance as the substance is not adequately characterised by taking into account carbon, hydrogen and oxygen only and omitting nitrogen and sodium.
AES is not a potential explosive and does not have potential for rapid energy release. - Executive summary:
3.1 Reactive Groups:
The appraisal of the molecular structure indicates no risk of rapid decomposition. AES does not contain any of the structural features mentioned in the UN Recommendations.
3.2 Oxygen Balance:
Taking carbon, hydrogen and oxygen into consideration only and based on a molecular formula of C16H17NO14Na6 x 3H2O with a molecular weight of 639, the oxygen balance is above -200.
3.3 Calorimetric Tests:
The exothermic decomposition energy was determined using Differential Scanning Calorimetry in a closed, gold plated high pressure vessel (DSC).
The decomposition energy was found to be about 208 J/g thus being below the UN limit of 500 J/g. The onset point of the exothermic peak was at about 246 °C.
