Specific details on test material used for the study:
Name: Vinylcyclohexan
CAS No.: 695-12-5
Batch No.: VCH/7/17K1
Purity: 99.8 % (GC)
Description: Clear colourless liquid
Key result
Parameter:
other: Thermal stability (Differential Scanning Calorimetry)
Remarks on result:
other: In the DSC-measurement the energy of the exothermic decomposition of the test item Vinylcyclohexane was below the threshold of -500 J/g. Therefore, further tests for explosive properties had not to be performed.

Results

Thermal stability (DSC)

In the temperature range of 160 – 220 °C, an exothermal effect was detected, with an average decomposition energy of approx. ‑70 J/g. Starting at approx. 230 °C a pressure rise could be observed, but the crucibles remained closed. No further thermic effects occurred up to the maximum temperature of 500 °C.

Due to the decomposition energy being below the threshold of -500 J/g, further tests for explosive properties did not have to be performed.

Interpretation of results:
GHS criteria not met
Conclusions:
The explosive properties of the test item vinylcyclohexane were investigated with Differential Scanning Calorimetrie. Due to the decomposition energy being below the threshold of -500 J/g, further tests for explosive properties did not have to be performed.
Executive summary:

In the DSC-measurement the energy of the exothermic decomposition of the test item vinylcyclohexane was below the threshold of -500 J/g. Therefore, further tests for explosive properties had not to be performed.

According to the results of the test on thermal stability, 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.

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