guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.14 (Explosive properties)

Deviations:

Specific details on test material used for the study:

- Analytical purity: 82.3%
- Purity test date: Not available
- Lot/batch No.: GN-8
- Expiration date of the lot/batch: Not available
- Appearance: Amber coloured, extremely viscous liquid
- Storage: In the dark at room temperature
- Additional information on test material used for the study: It was attempted to purify the substance to a purity of >80% by using an alternative synthetic route, as opposed to the usual commercial route of synthesis which results in a purity of the substance of approximately 40% in water. This alternative synthetic route generated the substance at 82.3% purity, however it also generated an impurity (methanol at 4.0%) which is not present in the commercial substance. Based on the classification and labelling of methanol, it is considered that this additional impurity would not have an influence on any of the endpoints discussed in this dossier other than the acute oral toxicity study. Therefore all studies (including the one covering this endpoint) contained in this dossier (other than the acute oral toxicity study) were conducted on the 82.3% pure substance containing the 4.0% methanol impurity. The acute oral toxicity study has been conducted on the commercially generated substance at a purity of approximately 40% in water.

Interpretation of results:

GHS criteria not met

Conclusions:

The test material was demonstrated to have no explosive properties.

Executive summary:

The explosive properties of the test material were investigated in a GLP-compliant study performed according to the test methods described in the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria. Based on the results of the tests performed (BAM fall hammer test, Koenen steel tube test), it was concluded that the test material had no explosive properties and needs not to be classified as an explosive substance.
