Remarks on result:
other: one exothermic peaks up to 350 °C with a total energy release of 229.98 J/g

Screening evaluation

Analysis of the molecular structure of Disperse Violet 057 revealed, that no chemical alert structures are present in the molecule.

Calculation of the oxygen balance according to the above mentioned formula is -177.81 and therefore slightly higher than the trigger value of -200.

Determination of the exothermic decomposition energy

The curve displays one exothermic peaks up to 350 °C with a total energy release of 229.98 J/g. This peak is considered to represent substance decomposition. As a result, the overall energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.
Executive summary:

No experimental data to determine the explosiveness of Disperse Violet 057 is available. However, an expert judgment was done based on the screening procedure as described in:

- CLP, Annex I, Part 2, paragraphs 2.1.4.2 and 2.1.4.3

- Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria

- Technical Guidance Document on the Information Requirements for REACH, Part 2 EWG 1-7, REACH Implementation Project (RIP) 3.3 Phase 2, chapter 7.1.11.3

Analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore, the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 and no further testing is required.

non explosive

Additional information

No experimental data to determine the explosiveness of Disperse Violet 057 is available. However, an expert judgment was done based on the screening procedure as described in:

- CLP, Annex I, Part 2, paragraphs 2.1.4.2 and 2.1.4.3

- Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria

- Technical Guidance Document on the Information Requirements for REACH, Part 2 EWG 1-7, REACH Implementation Project (RIP) 3.3 Phase 2, chapter 7.1.11.3

Analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore, the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 and no further testing is required.

Justification for classification or non-classification

The substance was concluded to be not an explosive based on the expert judgment, hence it does not warrant classification as per the criteria of Regulation (EC) No. 1272/2008.
