Version / remarks:

The screening procedure is 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

Deviations:

no

Principles of method if other than guideline:

Screening evaluation as recommended by the above selected test guidelines

GLP compliance:

no

Specific details on test material used for the study:

None

Parameter:

other: Exothermic decomposition energy

Remarks on result:

other: Exothermic decomposition energy: The curve displayed a exothermic peak between 260 and 350 °C with an overall energy release of 314.58 J/g, which is below the critical trigger level of 500 J/g and the onset of energy release being below 500 °C.

Parameter:

other: calculated chemical oxygen

Remarks on result:

other: calculated chemical oxygen balance is above the trigger value of -200,

- Analysis of the molecular structure of the chemical revealed that no such chemical alert structures are present in the molecule.

- Calculation of the oxygen balance according to the above mentioned formula is -180.44 and therefore higher than the trigger value of -200.

- Exothermic decomposition energy: The curve displays one exothermic peak between 260 and 350 °C with an overall energy release of 314.58 J/g. 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.

Executive summary:

Explosive properties of the test substance were evaluated in a screening procedure as recommended by the internationally accepted guidelines. Analysis of the chemical structure revealed no alerts for explosive properties. The calculated chemical oxygen balance was 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 was considered to be non-explosive according to Regulation (EC) 1272/2008 and no further testing is required.

Description of key information

Explosive properties of Disperse Red 092 were evaluated in a screening procedure as recommended by the internationally accepted guidelines. Analysis of the chemical structure revealed no alerts for explosive properties. The calculated chemical oxygen balance was 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 was considered to be non-explosive according to Regulation (EC) 1272/2008 and no further testing is required.

Key value for chemical safety assessment

Explosiveness:

non explosive

Justification for classification or non-classification

As the Disperse Red 092 has been considered to be non-explosive based on the expert statement, hence does not warrant classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
