Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.

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.

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.

Executive summary:

In an indipendent study the ignition temperature was determined to be above 500 °C.

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.
