- Endpoint:
- explosiveness
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 18 October 1999 -03 November 1999
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Deviations:
- no
- GLP compliance:
- yes
- Parameter:
- other: More sensitive to shock than m-dinitrobenzene
- Remarks:
- migrated information
- Remarks on result:
- negative (not further specified)
- Parameter:
- other: More sensitive to friction than m-dinitrobenzene
- Remarks:
- migrated information
- Remarks on result:
- not measured/tested
- Remarks:
- Not applicable because test substance is a liquid at room temperature.
- Parameter:
- other: Explosive under influence of flame
- Remarks:
- migrated information
- Remarks on result:
- negative (not further specified)
- Remarks:
- Substance ignited between 51 and 69 seconds, producing a yellow flame only.
- Parameter:
- other: Explosive (not specified)
- Remarks:
- migrated information
- Remarks on result:
- negative (not further specified)
- Key result
- Method:
- other: Koenen apparatus according to BAM 785-0004
- Parameter:
- other: Thermal and mechanical sensitivity
- Result:
- negative, no explosion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a GLP study, EC# 434-650-5 was not explosive as measured by thermal and mechanical sensitivity assays conducted in accordance with EU Method A.14.
- Executive summary:
In a GLP study, the explosiveness of EC# 434-650-5 was determined using a Koenen test apparatus (for the determination of sensitivity to heat) and a fall hammer (for the determination of sensitivity to shock) in accordance with EU Method A.14.
With the former, a steel tube (75x24 mm) was filled with around 30 g test substance to a level of 60 mm. A 6 mm orifice plate was fitted to the tube before placing in the apparatus, where burners of propane gas were ignited and allowed to burn for 5 minutes. The test was repeated with a 2 mm orifice plate. The substance ignited between 51 and 69 seconds, producing a yellow flame only. There was no audible explosion and the steel tube remained intact.
With the latter, one drop of test substance was put in a die and placed on an anvil. A 10 kg weight was released from a height of 0.4 m above the anvil, onto the test substance. There was no audible explosion and the material did not ignite.
These results indicate that EC# 434-650-5 does not possess explosive properties.
In view of the structural and chemical similarities, it is considered that the results of this study can be used for read-across to EC# 457-320-2.
- Endpoint:

In view of the structural and chemical similarities, it is considered that the results of this study can be used for read-across to EC# 457-320-2.
Furthermore, the substance does not contain any chemical groups associated with explosive properties, therefore a study on the substance itself is not needed.
- Endpoint:
- explosive properties of explosives
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Description of key information
An explosivity does not need to be conducted as the substances does not contain any chemical groups associated with explosivity.
Moreover, a GLP study on read-across substance EC# 434-650-5 was not explosive as measured by thermal and mechanical sensitivity assays conducted in accordance with EU Method A.14. The result can be read-across to EC #457-320-2.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
