Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- other: Expert statement
- Adequacy of study:
- key study
- Study period:
- 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- The screening procedure described in the following guidance was used:
- 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: Presence of chemical structures associated with explosive properties
- Remarks on result:
- other: no structures associated with explosive properties are present in the molecule
- Parameter:
- other: Oxygen balance
- Value:
- -128.36
- Remarks on result:
- other: slightly higher than the trigger value of -200
- Parameter:
- other: Exothermic decomposition energy
- Remarks on result:
- other: The curve displays one peak between 280 and 350 °C which is considered to represent substance decomposition energy. 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:
- FAT 20011 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 for assessment of explosiveness according to EU Method A.14 or comparable methods for Acid Blue 317 are available. Hence an expert judgment based on the screening procedure as described in below mentioned guidelines was conducted:
- CLP Regulation, 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 revealed 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) 1272/2008 and no further testing is required.
Reference
Screening evaluation
Analysis of the molecular structure of Acid Blue 317 revealed, that no chemical alert structures associated with explosive properties are present in the molecule.
Calculation of the oxygen balance according to the above-mentioned formula is -128.36 and therefore higher than the trigger value of -200.
Determination of the exothermic decomposition energy
The curve displays one peak between 280 and 350 °C which is considered to represent substance decomposition energy. 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.
Description of key information
No experimental test data for assessment of explosiveness according to EU Method A.14 or comparable methods for Acid Blue 317 are available. Hence, an expert judgment based on the screening procedure as described in below mentioned guidelines was conducted:
- CLP Regulation, 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 revealed 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) 1272/2008 and no further testing is required.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
Acid Blue 317 is considered to be non-explosive based on the expert statement, hence it does not warrant classification according to the 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).
