Reference
Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
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:
see attached study report
Deviations:
no
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Parameter:
other: Thermal stability (DSC)
Value:
400
Remarks on result:
not thermal sensitive if heated under defined confinement
Remarks:
Value = + 400 J/g, so endotherm

In the temperature range at 400 – 480 °C an endothermic effect can be observed. Up to the maximum test temperature of 500 °C no significant exothermic effects were detected during DSC testing.

As no significant exothermic effects were observed up to 500 °C no further tests for explosive properties has to be performed.

Interpretation of results:
other: EU GHS criteria not met
Conclusions:
In the DSC-measurement of the test item no significant exothermic effects were observed up to 500 °C. Therefore, further tests for explosive properties did not have to be performed.
Executive summary:

The explosive properties of the test item were assessed in a non-GLP study according to UN Manual of Tests and Criteria: Part I. In the DSC-measurement of the test item no significant exothermic effects were observed up to 500 °C. Therefore, further tests for explosive properties did not have to be performed.

According to the results of the test on thermal stability and explosive properties, the test item is classified as following:

UN Transport Regulation: The test item does not have to be classified as explosive substance in class 1 according to the UN Transport Regulation.

GHS (CLP Regulation EC 1272/2008: Annex 1: 2.1): The test item does not have to be classified as explosive substance according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.1, respectively.

Description of key information

The explosive properties of the test item were assessed in a non-GLP study according to UN Manual of Tests and Criteria: Part I. In the DSC-measurement of the test item no significant exothermic effects were observed up to 500 °C. Therefore, further tests for explosive properties did not have to be performed.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

According to the results of the test on thermal stability and explosive properties, the test item is classified as following:

UN Transport Regulation: The test item does not have to be classified as explosive substance in class 1 according to the UN Transport Regulation.

GHS (CLP Regulation EC 1272/2008: Annex 1: 2.1): The test item does not have to be classified as explosive substance according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.1, respectively, because no exothermic effects were observed during testing via DSC up to 500 °C
