Parameter:
other: Decomposition energy
Value:
-430
Result:
result is considered "-" (negative)

In the temperature range of 170 - 330 °C an exothermic effect was observed with a decomposition energy of -410 J/g and -430 J/g, respectively.

Results of the DSC-measurements:

No.

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 the exothermic decomposition is 170°C.

Interpretation of results:
GHS criteria not met
Conclusions:
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 170°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 thermal stability experiment (DSC-measurement) the energy of the exothermic decomposition of the test item was < -500 J/g. The onset temperature for the exothermic decomposition was 170°C. Therefore, further tests for explosive properties had not to be performed.

The test item has no explosive properties according to the Regulation EC No. 440/2008 Method A.14. 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.

In the thermal stability experiment (DSC-measurement) the energy of the exothermic decomposition of the test item was < -500 J/g. The onset temperature for the exothermic decomposition was 170°C. Therefore, further tests for explosive properties had not to be performed.

The test item has no explosive properties according to the Regulation EC No. 440/2008 Method A.14. 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 170°C. Therefore, the test item does not have to be classified as explosive substance.
