Results and discussion

Flash point
Key result
Flash point:
128 °C
Atm. press.:
ca. 101 325 Pa

Any other information on results incl. tables

Preliminary Test: The estimated flash-point of the test item was 127 °C.

 

Main Study: Both experiments determined the flash-point of the test item to be 128 °C

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The flash-point of the test item was measured to be 128 °C.
Executive summary:

The flash-point of the test item was determined according EC Method A.9, ISO 2719 and ASTM D93, and measured to be 128 °C using the closed cup method. Based on these results, the test item does not meet the criteria for classification as a flammable liquid under EU CLP regulation/ GHS.
