In the temperature range of 110 - 330°C a broad endothermic effect and in the temperature range of 350 - 500 °C exothermic effects were observed with an overall decomposition energy of -110 J/g and > -210 J/g, respectively.

Due to the decomposition energy being below the threshold of -500 J/g, further tests for explosive properties did not have to be performed. The onset temperature for decomposition was 350°C.

Interpretation of results:
GHS criteria not met
Conclusions:
In the thermal stability test using DSC-measurement the energy of the exothermic decomposition of the test item was < -500 J/g. The onset temperature for the exothermic decomposition was 350°C. Therefore, further tests for explosive properties had not to be performed.
Executive summary:

The explosive properties of the test item were assessed according to Regulation EC No. 440/2008 Method A.14. Explosive Properties and OECD Test Guideline 113 (1981): Thermal Stability.

In the DSC-measurement the energy of the exothermic decomposition of the test item was < -500 J/g. The onset temperature for the exothermic decomposition was 350°C. Therefore, further tests for explosive properties had not to be performed. It is concluded that the test item has no explosive properties.

Description of key information

For this endpoint one study is available. The explosive properties of the test item were assessed according to Regulation EC No. 440/2008 Method A.14. Explosive Properties and OECD Test Guideline 113 (1981): Thermal Stability (DSC measurement).

In the DSC-measurement the energy of the exothermic decomposition of the test item was < -500 J/g. The onset temperature for the exothermic decomposition was 350°C. Therefore, further tests for explosive properties had not to be performed. It is concluded that the test item has no explosive properties.

Additional information

Justification for classification or non-classification

According to CLP Regulation EC 1272/2008: Annex 1: 2.1.4.3(c), a substance or mixture shall not be classified as explosive if organic substances contains chemical groups associated with explosive properties but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500°C.

This substance has an exothermic decomposition energy of < -500 J/g and the onset temperature of exothermic decomposition is 350°C. Therefore, the test item does not have to be classified as explosive substance.
