Link to relevant study record(s)
- Endpoint:
- explosiveness
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Guideline study (in accordance with the OECD and EU guidelines) and performed in a laboratory under DIN ISO/IEC 17025. The study is adequate but not described in detail, no detail on substance purity and batch used are reported.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- GLP compliance:
- no
- Remarks:
- performed in a laboratory under DIN ISO/IEC 17025
- Parameter:
- other: More sensitive to shock than m-dinitrobenzene
- Remarks:
- migrated information
- Remarks on result:
- other: no data
- Remarks:
- No impact sensitivity of the test item was observed.
- Parameter:
- other: More sensitive to friction than m-dinitrobenzene
- Remarks:
- migrated information
- Remarks on result:
- other: no data
- Remarks:
- No friction sensitivity of the test item was observed.
- Parameter:
- other: Explosive under influence of flame
- Remarks:
- migrated information
- Remarks on result:
- negative (not further specified)
- Remarks:
- No thermal sensitivity of the test item induced by heating under defined confinement was observed.
- Interpretation of results:
- non explosive
- Remarks:
- Migrated information
- Conclusions:
- The test item showed no explosive properties at all (no mechanical sensitivity and no thermal sensitivity).
The study is considered to be reliable with some restrictions.
Reference
Mechanical shock sensitivity: none of the six single tests with an impact energy of 40 J showed any sparking or exploding. Therefore the series with an impact energy of 7.5 J was not necessary. No impact sensitivity of the test item was observed.
Mechanical friction sensitivity: none of six single tests with a friction force of 360 N showed any visible or audible explosion or crackling or sparking. Therefore the series with a friction force of 120 N was not necessary. No friction sensitivity of the test item was observed.
Thermal sensitivity: after 11 s (at 2 mm orifice) and 13 s (at 6 mm orifice) in all single tests the start of a weak reaction was observed manifested by colouring the gas flames orange and by a short time emission of testing substance. After about 55 s (over-all time) the steel tubes became red glowing at 6 mm and at 2 mm orifice. At 6 mm orifice, after about 80 s smoking was visible and at 2 mm orifice, after about 65 s a slight blow off sound was to hear and a second minor emission of testing substance occurred. No further observation was made until the burners were turned off after 5 minutes. After cooling down all the tubes were unchanged. No thermal sensitivity of the test item induced by heating under defined confinement was observed.
Description of key information
Mechanical shock sensitivity: no, EU Method A.14, Mekelburger 2004
Mechanical friction sensitivity: no EU Method A.14, Mekelburger 2004
Thermal sensitivity: no EU Method A.14, Mekelburger 2004
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
This study the determination of the explosive properties was performed in accordance with the EU method A. 14., Official Journal of the European Communities, 92/69/EEC, No L 383, December 1992. The available data are considered reliable with some restrictions but adequate. Based on the results, the substance does not meet the criteria for classification under classification under Regulation (EC) No. 1272/2008.
Furthermore, according to the additional criteria for classification 2.1.4.3(a), of Regulation (EC) No. 1272/2008, Annex I, part 2, if the molecule does not contain functional groups associated with explosive properties, the substance shall not be classified. As a result, given the lack of functional groups indicating explosive properties, this substance does not meet the criteria for classification under 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).
