Explosiveness
Administrative data
Link to relevant study record(s)
- Endpoint:
- explosiveness, other
- Type of information:
- other: expert assessment
- 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
- Justification for type of information:
- None
- Qualifier:
- according to guideline
- Guideline:
- other: As per the screening evaluation recommnded in CLP, UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria as well as REACH
- Version / remarks:
- 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 - Deviations:
- no
- GLP compliance:
- no
- Specific details on test material used for the study:
- None
- Key result
- 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.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The substance is considered to be non-explosive based on the screening evaluation.
- Executive summary:
A screening for the explosive properties of the substance was carried out according to internationally accepted guidelines. Analysis of the chemical structure revealed one azo group representing a chemical alert structure for explosive properties. The oxygen balance was calculated to be -128.61 and therefore is higher than the trigger value of -200. The curve displayed one exothermic peak between 320 °C and 350 °C with a total energy release of 66.50 J/g which 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. 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 the substance revealed that one azo group representing a chemical alert structure for explosive properties is present in the molecule.
The oxygen balance was calculated to be -128.61 and therefore is higher than the trigger value of -200.
Determination of the exothermic decomposition energy:
The curve displayed one exothermic peak between 320 °C and 350 °C with a total energy release of 66.50 J/g which 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.
Description of key information
The substance is considered to be non-explosive.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
A screening for the explosive properties of the substance was carried out according to internationally accepted guidelines. Analysis of the chemical structure revealed one azo group representing a chemical alert structure for explosive properties. The oxygen balance was calculated to be -128.61 and therefore is higher than the trigger value of -200. The curve displayed one exothermic peak between 320 °C and 350 °C with a total energy release of 66.50 J/g which 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. 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.
Justification for classification or non-classification
Based on the outcome of a screening evaluation, the substance was considered to be non-explosive, hence no classification was required according to the CLP (Regulation 1272/2008) criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
