Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Qualifier:
- according to guideline
- Guideline:
- other: VDI-Richtlinie 2263
- Deviations:
- no
- Principles of method if other than guideline:
- The test substance was subjected to tests for thermal and mechanical sensitivity.
- GLP compliance:
- not specified
- Key result
- Parameter:
- other: test parameter not specified
- Remarks on result:
- not thermal sensitive if heated under defined confinement
- Remarks:
- The test substance was found to be glowing locally without spread of the flame. At a temperatures greater than 210°C, it was found to be annealing.
- Interpretation of results:
- study cannot be used for classification
- Conclusions:
- Like many other organic compounds, the test substance was found to have dust explosive properties under the study conditions.
For all concentrations from 100 g/m3 to 1000 g/m3 the dust explosion class was determined to be 1. - Executive summary:
Under the study conditions, the test substance was found to be weakly dust explosive (dust explosion class 1, St 1), but this does not fulfil the criteria of an explosive substance as given by EG A.14.
- Endpoint:
- explosive properties of explosives
- Type of information:

- Key result
- Parameter:
- other: Criteria according to UN class 4.1 resp. 4.2
- Remarks on result:
- other: does not qualify for UN 4.1 resp. 4.2
- Executive summary:
Based on the results of a Bowes-Cameron-Cage-Test the substance was classified as not falling under the criteria of UN class 4.1 resp. 4.2.
- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:

- sensitiveness to impact: impact energy (J)
- Value:
- 500
- Executive summary:
In an indipendent study the ignition temperature was determined to be above 500 °C.
Referenceopen allclose all
The test substance was found to be glowing locally without spread of the flame. At a temperature greater than 210°C, it was found to be annealing.
Description of key information
The explosiveness was determined according to an internal protocol (Reinartz, 1989). Under the study conditions, the test substance was found to be weakly dust explosive (dust explosion class 1, St 1), but this does not fulfill the criteria of an explosive substance as given by EG A.14. Additionally, the substance was subject to a Bowes-Cameron-Cage-Test to decide on UN classification under class 4.1 resp. 4.2. Based on this test, the substance does not fall under the criteria of UN class 4.1 resp. 4.2. In a third independent test, the ignition temperature was determined to be above 500°C.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Under the conditions of the above-mentioned studies, the test substance was found to be weakly dust explosive, but this does not fulfil the criteria of an explosive substance as given by EG A.14 or UN class 4.1 resp 4.2.
Justification for classification or non-classification
No classification applies since the substance does not ignite at temperatures below 500°C and was not explosive in the Bowes-Cameron-Cage test. The substance was found to be weakly dust explosive, but this property does not fulfil the criteria for classification under EG A.14.
