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
