Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- other: expert statement
- Adequacy of study:
- key study
- Study period:
- 07 July 2021
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: See remark
- 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:
- 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 - GLP compliance:
- no
- Parameter:
- other: oxygen balance
- Remarks on result:
- other: oxygen balance according to the above-mentioned formulas is -113.78 for main constituent 1 and -108.58 for main constituent 2 and therefore above the trigger value of -200.
- Parameter:
- other: Determination of the exothermic decomposition energy
- Remarks on result:
- other: energy release of about 243 J/g which demonstrated no critical energy release below the critical value of 500 J/g
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance is considered as non-explosive.
- Executive summary:
Test substance was assessed basis of expert statement for explosive properties of FAT 40879. Analysis of the molecular structures revealed, that that the molecule contains an unsaturated C-C bond and azo groups linked to aromatic rings in main constituent 1 as well as in main constituent 2 both of which might be associated with explosive properties according to the UN Recommendations and the Handbook of Reactive Chemical Hazards. Calculation of the oxygen balance according to the above-mentioned formulas is -113.78 for main constituent 1 and -108.58 for main constituent 2 and therefore above the trigger value of -200. The curve displays one exothermic peak up to 350 °C with an energy release of about 243 J/g, while this peak is considered to represent test substance decomposition. As a result, the energy release is below a critical trigger level of 500 J/g with the onset of energy release being below 500 °C. In summary, analysis of the chemical structure reveals some 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 no critical energy release below the critical value of 500 J/g. Therefore, the substance is judged nonexplosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.

Additional information
Justification for classification or non-classification
The test substance 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
