other: Structural assessment
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
no guideline followed
Principles of method if other than guideline:
A structural assessment to identify the presence of chemical groups associated with explosive properties.

other: Structural assessment
Parameter:
other: Not applicable for structural assessment
Result:
result is considered "-" (negative)
Remarks:
Based on structural assessment.
Remarks on result:
not measured/tested
Remarks:
Structural assessment conducted

An examination of the structure of the test material reveals that it contains no groups which are known to be associated with explosive properties. Therefore the oxygen balance of the test material is not required. It should be noted however, there is an ‘R’ functional group present that usually indicates a hydrogen or hydrocarbon side chain. As these groups are not associated with explosive properties, this does not affect the conclusion of the assessment.

 

Interpretation of results:
other: non-explosive
Conclusions:
The structural examination of the test material suggests it is not likely to possess explosive properties.
Executive summary:

An explosive substance may be defined as a substance which may explode under the effect of flame or which is sensitive to shock or friction. Assessments of the structure of a compound, alongside a calculation of the oxygen balance (if required), can give an indication of the likelihood of the substance possessing explosive properties.

A substance may be explosive if its molecules contain bond groupings which confer upon them explosive properties.

Justification for classification or non-classification

In accordance with Section 7.11 of Column 2 of Annex VII of the REACH Regulation, it is considered justified to omit the explosivity testing on the grounds that, from the compositional description and the structural formula of the substance, it can be concluded that the substance does not exhibit explosive properties as there are no functional groups associated with explosive properties or tendencies present. Thus, this substance should not be classified as dangerous according to the criteria for explosivity.
