Description: Clear colourless liquid - Key result
- Flash point:
- 10.5 °C
- Atm. press.:
- 1 atm
- Remarks on result:
- other: Average corrected flash point rounded down to the nearest multiple of 0.5 °C
- Interpretation of results:
- Category 2 (highly flammable liquids) based on GHS criteria
- Conclusions:
- The test item Vinylcyclohexane has a flash point of 10.5 °C (average corrected and rounded down to the nearest multiple of 0.5 °C), according to Regulation EC No. 440/2008 Method A.9. Flash Point and DIN EN ISO 13736 (2013).
- Executive summary:
The test item Vinylcyclohexane has a flash point of 10.5 °C (average corrected and rounded down to the nearest multiple of 0.5 °C), according to Regulation EC No. 440/2008 Method A.9. Flash Point and DIN EN ISO 13736 (2013). Therefore, Vinylcyclohexane is classified as follows:
UN Transport Regulation: As the test item has a boiling point of 128 °C (SDS) (> 35 °C) and a measured flash point of 10.5 °C (< 23 °C), it has to be classified in class 3 as flammable liquid of Packaging Group II.
GHS (CLP Regulation EC 1272/2008 Annex 1: 2.6): As the test item has a boiling point of 128 °C (SDS) (> 35 °C) and a measured flash point of 10.5 °C (< 23 °C), it has to be classified as highly flammable liquid of category 2 and has to be marked with the warning “H225: highly flammable liquid and vapour”.

In the main test the lowest temperature where an ignition was observed was 10.0 °C. The mean measured flash point is corrected to the ambient pressure to be 10.9 °C.
The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 10.5 °C
Description of key information
The test item Vinylcyclohexane has a flash point of 10.5 °C (average corrected and rounded down to the nearest multiple of 0.5 °C), according to Regulation EC No. 440/2008 Method A.9. Flash Point and DIN EN ISO 13736 (2013). Therefore, Vinylcyclohexane is classified as follows:
UN Transport Regulation: As the test item has a boiling point of 127 °C (CRC Handbook) (> 35 °C) and a measured flash point of 10.5 °C (< 23 °C), it has to be classified in class 3 as flammable liquid of Packaging Group II.
GHS (CLP Regulation EC 1272/2008 Annex 1: 2.6): As the test item has a boiling point of 127 °C (CRC Handbook) (> 35 °C) and a measured flash point of 10.5 °C (< 23 °C), it has to be classified as highly flammable liquid of category 2 and has to be marked with the warning “H225: highly flammable liquid and vapour”.
