Remarks:
Under COLUMN 2 “SPECIFIC RULES FOR ADAPTATION FROM COLUMN 1” in the REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 18 December 2006, it states The study does not need to be conducted if: “there are no chemical groups associated with explosive properties present in the molecule” accordingly “The structure of the test material was assessed for chemical groups that imply explosive properties. Examples of such groups are C-C unsaturated, C-metal, N-metal, contiguous oxygen atoms, contiguous nitrogen atoms, N-halogens, O-halogens, N-O.” A study was conducted to estimate the explosive properties of Acid Yellow RN 2903 based on the UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Fourth revised edition, 2003, Appendix 6, “Orange Book”) where a set of criteria is compiled to identify materials being potential explosives. Applying the internationally recognised UN Recommendation criteria, Acid Yellow RN 2903 is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed. Thus it can be concluded beyond a reasonable doubt, that Acid Yellow RN 2903 is not a potential explosive and does not have a potential for rapid energy release. Nevertheless, this judgment is in respect to classification; it does not necessarily mean that any processing hazards can be discounted.

Results

The structure of the test material was assessed for chemical groups that imply explosive properties, there are no such groups present in the structure. The decompsition energy based on a DSC scan does not exceed the UN limit of 500 J/g.

Applicant's summary and conclusion

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
Based on the chemical structure and a DSC of the test material the result for the explosive properties has been predicted negative.
Executive summary:

Applying the internationally recognised UN Recommedation criteria, Acid Yellow RN 2903 is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed.

 

Thus it can be concluded beyond a reasonable doubt, that Acid Yellow RN 2903 is not a potential explosive and does not have a potential for rapid energy release. Nevertheless, this judgment is in respect to classification; it does not necessarily mean that any processing hazards can be discounted.
