Version / remarks:
2003
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Version / remarks:
Council Regulation (EC) No. 440/2008 of 30 May 2008
Deviations:
no
GLP compliance:
yes (incl. QA statement)

Because the difference between the two main test measurements was <= 3.5 (mean value x 0.029), a second main test was not necessary.

Interpretation of results:
GHS criteria not met
Conclusions:
A flash point value of 120°C at 1013 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.

Description of key information

Flash point: 120°C at 1013 hPa (ISO 2719)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
120 °C

Additional information

There are four reliable studies for the flash point of the submission substance. A measured flash point value of 120°C at 1013 hPa was determined for the substance using a non-equilibirum closed-cup method in accordance with ISO 2719 Test Method and in compliance with GLP. The result is considered to be reliable and is selected as key study. In other reliable studies, flash point values of 98°C, 107°C and 116.7°C were determined for the substance using appropriate test methods. The key study has been selected as the study with the highest reliability and which was recently conducted.

In available secondary sources to which reliability could not be assigned, flash point values of 121°C and 136°C were reported for the substance.

Differences in the flash point result could be due to differences in purity of the commercial samples tested and the test method used.

A measured flash point of 120°C and a predicted boiling point of 240°C, indicate that the substance should not be classified for flammability according to the criteria of Regulation (EC) No. 1272/2008.
