Again, the flame is extinguished by evaporating test item at 133 °C. Therefore, the test item has no flash point up to 133 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item PU-2021-971 does not have a flash point up to 133 °C according to Regulation (EC) No 440/2008 Method A.9. Flash Point and DIN EN ISO 2719 (2021).
According to the results of the test on the flash point, the test item is classified as follows:
UN Transport Regulation: As the test item has no flash point up to 133 °C (> 60 °C), it has not to be classified as flammable liquid of UN Class 3.
Attention: Under the transport regulation special rules apply to viscous compounds.
GHS (CLP Regulation (EC) No 1272/2008 Annex I: 2.6): As the test item has no flash point up to 133 °C (> 60 °C), it has not to be classified as flammable liquid.
