Results and discussion

Flash point
Key result
Flash point:
> 300 °C
Atm. press.:
ca. 101.3 kPa

Any other information on results incl. tables

Pre-tests were performed between 25.0°C and 300°C but no flash was detected. However the technician observed that the flame of the ignitor enlarged when the ignitor was dipped into the test cup from 170°C but no flash was observed.

Moreover the flash point of the reference substances glycerol and CRM respects the checking cards limits.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The corrected flash point of the test item was determined to be over 300°C at 101.3 kPa as no flash was detected by the apparatus. However, it was observed that the test item releases vapors which feed the flame of the ignitor from 170°C.
