Explosiveness
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:
- 20-22 June 2017
- Reliability:
- 1 (reliable without restriction)
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Part I: Classification procedures, test methods and criteria relating to explosives of Class 1
- Version / remarks:
- UN Handbook “Recommendations on the Transport of Dangerous Goods; Manual of Tests and Criteria”; sixth revised edition, UN, 2015, Section 20.2.1, 20.3.3.3 and Apendix 6 / Screening test
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guidelines for the Testing of Chemicals, Method No. 113, adopted 12. May 1981: “Screening Test for Thermal Stability and Stability in Air”
- Version / remarks:
- 1981
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Date of inspection: 13-14 October 2014; Date of signature: 8 April 2015
- Key result
- Parameter:
- other: DSC screening test
- Remarks on result:
- negative (not further specified)
- Remarks:
- no significant exothermic event was observed during the DSC run
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- A screening via DSC (differential scanning calorimetry) was conducted.
During the DSC run (from 0 to 520 °C) no significant exothermic event was observed. The acceptance procedures for Class 1 explosives need not to be applied.
No additional testing is required. The substance shall not be classified as explosive according to Regulation (EC) N°1272/2008 (CLP). - Executive summary:
The thermal stability of the test substance was tested with Differential Scanning Calorimetry, in accordance with conditions recommended in UN MTC screening procedure/OECD guideline. Up to the maximum test temperature of 520°C, no significant exothermic event was observed.

After the test the crucible was visually unchanged. The crucible was opened, a black residue was observed, the inside sealed gold ring was black discoloured. |
Finally, during the DSC run (from 0 to 520 °C) no significant exothermic event was observed.
The measurement of indium after calibration met the validity criteria. Therefore, the result of the study is considered valid.
Description of key information
DSC screening test: no significant exothermic event was observed up to 520°C.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
A fully reliable experimental study, conducted in accordance with conditions recommended in UN MTC screening procedures/OECD guideline, and under GLP, is available. It is considered as a key study. The result is retained as key data.
No further testing is required.
Justification for classification or non-classification
During the DSC run (from 0 to 520 °C) no significant exothermic event was observed. The acceptance procedures for Class 1 explosives need not to be applied.
No additional testing is required. The substance shall not be classified as explosive according to Regulation (EC) N°1272/2008 (CLP).
