Administrative data
Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14 September 2017 – 04 January 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Parameter:
- other: Explosiveness
- Remarks on result:
- other: theoretical assessment conducted.
- Remarks:
- No groups identified associated with explosive properties.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Examination of the structural formula for the sample indicated that there are no chemical groups associated with explosive properties. In addition, the sample is inorganic and the oxygen balance is therefore not applicable. Based on this combination of factors, it is beyond reasonable doubt that the material will not exhibit explosive properties.
- Executive summary:
According to the OECD testing methods publication, test A14 need not be carried out when examination of the structural formula establishes beyond reasonable doubt that the substance has no explosive properties. Examination of the structural formula for the sample indicated that there are no chemical groups associated with explosive properties. In addition, the sample is inorganic and the oxygen balance is therefore not applicable. Based on this combination of factors, it is beyond reasonable doubt that the material will not exhibit explosive properties.
Reference
It states in the UN Transport of Dangerous Goods, Manual of Tests and Criteria that explosive properties are associated with the presence of certain chemical groups in a molecule which can react to produce very rapid increases in temperature or pressure. A screening procedure was therefore be used to identify the presence of such reactive groups and the potential for energy release in dilithium tetraborate.
Explosives testing need not be applied where:
(a) there are no chemical groups associated with explosive properties present in the molecule. Examples of explosive groups are given in Table 1.
(b) the substance contains chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than -200.
(c) the organic substance or a homogeneous mixture of organic substances contain chemical groups associated with explosive properties but the exothermic decomposition energy is less than 500 J.g-1 and the onset of exothermic decomposition is below 500°C. The exothermic decomposition energy may be determined using a suitable calorimetric technique.

Examination of the structural formula for the sample indicated that;
(i) There are no chemical groups associated with explosive properties (Table 1).
(ii) The sample is inorganic and the oxygen balance is therefore not applicable.
Based on this combination of factors, it is beyond reasonable doubt that the material will not exhibit explosive properties. No further testing according to EU method A14 needs to be conducted.
Description of key information
Examination of the structural formula for the sample indicated that there are no chemical groups associated with explosive properties. In addition, the sample is inorganic and the oxygen balance is therefore not applicable. Based on this combination of factors, it is beyond reasonable doubt that the material will not exhibit explosive properties.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
Examination of the structural formula for the sample indicated that there are no chemical groups associated with explosive properties. In addition, the sample is inorganic and the oxygen balance is therefore not applicable. Based on this combination of factors, it is beyond reasonable doubt that the material will not exhibit explosive properties. No classification is therefore required.
