Reference

Reference 1

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 the substance is an organic substance or mixture containing chemical groups associated with explosive properties, but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500°C

Reason / purpose for cross-reference:

data waiving: supporting information

Reference 2

Endpoint:

explosive properties of explosives

Type of information:

other: expert statement

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: see 'Remark'

Remarks:

The explosive properties of test substance were estimated based on the UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Annex 6, Orange Book, 3d edition, 1999) where a set of criteria is compiled to identify materials being potential explosives.

Qualifier:

according to guideline

Guideline:

other: UN Recommendations on the transport of dangerous goods (Manual of tests and Criteria, Annex 6, Orange book, 3rd edition, 1999)

Deviations:

no

GLP compliance:

no

1. Reactive Groups

The appraisal of the molecular structure indicates that the molecule contains an olefinic group and several aromatic rings which might be associated with explosive properties according to the UN Recommendations and the Handbook of Reactive Chemical Hazards. Other chemical groups associated with explosive properties as compiled in these documents are not present. In absence of other criteria or in case of reasonable doubt with respect to rapid decomposition, this finding would lead to the recommendation for experimental testing.

2. Oxygen Balance

The oxygen balance is not considered relevant for the evaluation of the explosive properties of this substance as it is not adequately characterised by taking into account carbon, hydrogen and oxygen only and omitting nitrogen and sulphur. The evaluation as based on

criteria 1 and 3 is fully reliable even without oxygen balance data.

3. Calorimetric Tests

The exothermic decomposition energy was determined using Differential Scanning Calorimetry in a closed, gold plated high pressure vessel (DSC). The calorimetric test is of special irnportance for the evaluation of compounds containing chemical groups associated

with explosive properties (see item 1). Three broad peaks were detected between room temperature and 500°C. The total of their decomposition energy was found to be about 151 J/g thus being significantly below the UN limit of 500 J/g. The onset points of the exothermic peaks were at about 224, 314 and 360°C.

Interpretation of results:

GHS criteria not met

Remarks:

CLP Implementation.

Conclusions:

The product is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed.

Executive summary:

The explosive properties of test substance were estimated based on the UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Annex 6, Orange Book, 3d edition, 1999) where a set of criteria is compiled to identify materials being potential explosives. The test substance is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed. The result of item 2 (oxygen balance) is not considered relevant for this substance as the substance is not adequately characterised by taking into account carbon, hydrogen and oxygen only and omitting nitrogen, sulphur and halogens. Thus it can be concluded beyond a reasonable doubt, that the test substance is not a potential explosive and does not have a potential for rapid energy release.

Description of key information

Key study (expert statment): The explosive properties of test substance were estimated based on the UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Annex 6, Orange Book, 3d edition, 1999) where a set of criteria is compiled to identify materials being potential explosives. The test substance is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed. The result of item 2 (oxygen balance) is not considered relevant for this substance as the substance is not adequately characterised by taking into account carbon, hydrogen and oxygen only and omitting nitrogen, sulphur and halogens. Thus it can be concluded beyond a reasonable doubt, that the test substance is not a potential explosive and does not have a potential for rapid energy release.

Data waiving: In accordance with column 2 of REACH Annex VII, the study does not need to be conducted since the organic substance contains chemical groups associated with explosive properties, but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500 ºC.

Key value for chemical safety assessment
