Key result
Parameter:
other: DSC
Remarks on result:
other: The exothermic effect at 445 °C of -70 J/g² is below the threshold of 500 J/g² and so not significant for explosions.

- The exothermic effect at 445 °C of -70 J/g² is below the threshold of 500 J/g² and so not significant for explosions.

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

Interpretation of results:
other: Not classified in accordance with EU Criteria.
Conclusions:
Under the conditions of this study the test material is not explosive. 
Executive summary:

The explosivity of the test material was investigated in accordance with the standardised guideline UN Class 1 and EU Method A,14, using differential scanning calorimetry.

The prepared crucibles (crucible with test material and reference crucible) were placed in the DSC apparatus. Both crucibles were heated up from room temperature to 500 °C with a heating rate of 5 K/min.

The exothermic effect at 445 °C of -70 J/g² is below the threshold of 500 J/g² and so not significant for explosions.

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

Under the conditions of this study the test material was determined to be not explosive. 

Description of key information

Under the conditions of this study the test material is not explosive. 

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The explosivity potential of the test material was investigated in accordance with the standardised guideline UN Class 1, using differential scanning calorimetry. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).

The prepared crucibles (crucible with test material and reference crucible) were placed in the DSC apparatus. Both crucibles were heated up from room temperature to 500 °C with a heating rate of 5 K/min.

The exothermic effect at 445 °C of -70 J/g² is below the threshold of 500 J/g² and so not significant for explosions.

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

Under the conditions of this study the test material was determined to be not explosive. 

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to explosive properties.
