Description of key information
The result for explosive properties was predicted negative based on the chemical structure of the test item and this prediction was confirmed experimentally (EU Method A.14).
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Screening test
A screening test was performed according to guidelines given in ASTM E2019, British Standard 5958 and European Standard: IEC 1241 -2 -3. The test allows the test substance to be classified as Type A explosible or Type B non-explosible. The test substance was determined to be Type A (Explosible) indicating that the test substance, when in the form of a dust cloud, will explode if exposed to an ignition source.
Prediction of explosive properties
GUIDELINE
The prediction was undertaken using a procedure designed to be compatible with Method A.14 Explosive Properties of Commission Regulation (EC) No 440/2008 (30 May 2008).
RESULTS
No structural alerts associated with explosive properties were identified within the chemical structure of the test item.
CONCLUSION
The result for explosive properties was predicted negative based on the chemical structure of the test item.
Determination of explosive properties
GUIDELINE
The determination was carried out using BAM friction, BAM fall hammer and Koenen steel tube apparatus in a procedure designed to be compatible with Method A.14 Explosive properties of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 830.6316 of the OCSPP guidelines.
RESULTS
The results of the BAM friction test, BAM fall hammer test and Koenen steel tube test were all negative.
CONCLUSION
The test item was determined not to have explosive properties.
Justification for classification or non-classification
The result for explosive properties was predicted negative based on the chemical structure of the test item and the prediction was confirmed in an experimental investigation (EU Method A.14). Classification in accordance with Regulation (EC) No 1272/2008 is therefore unnecessary.
