Results and discussion
Flash point
- Flash point:
- 122 °C
- Atm. press.:
- 101.325 kPa
- Remarks on result:
- other: corrected to atmospheric pressure
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The results of the main tests are:
First determination: Flash point, corrected for atmospheric pressure: 123.0 ºC
Second determination: Flash point, corrected for atmospheric pressure: 122.0 ºC
The results of the two tests were averaged and round off to the nearest 0.5°C to obtain the final flash point value:
Flash point Hydroxy DHLL: 122.0 °C - Executive summary:
The flash point of Hydroxy DHLL was determined by the Pensky-Martens method according to ISO 2719/EU Method A.9.
The flash point is 122.0 °C
