Guideline:

other: Expert statement

Principles of method if other than guideline:

Expert judgment 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

GLP compliance:

no

Specific details on test material used for the study:

Name: FAT 36091

Parameter:

other: Determination of the exothermic decomposition energy

Remarks on result:

other: The overall energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.

Screening evaluation:

Analysis of the molecular structure revealed that no such chemical alert structures are present in the molecule. Calculation of the oxygen balance according to the above mentioned formula is -141.54 and therefore higher than the trigger value of -200.

Determination of the exothermic decomposition energy:

The curve displays one exothermic peak up to 350 °C with total energy release of about 802.71 J/g. As a result, the overall energy release is above 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 test data according to EU Method A.14 or comparable methods are available for Disperse yellow 211. Hence an expert judgment based on the screening procedure as described in below mentioned guidelines was conducted:

- 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

In summary, analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200 and the determination of the exothermic decomposition energy demonstrated an energy release above the critical value of 500 J/g. Additional data available for the related sales products revealed a risk for dust explosibility but not for spontaneous deflagration. Production of flammable decomposition gases have been noted while the ignition temperature was determined to 440 °C. As a conclusion 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.
