Link to relevant study record(s)

Reference

Endpoint:

flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

10/12/2014

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: Conducted at a GLP accredited laboratory

Qualifier:

according to guideline

Guideline:

EU Method A.9 (Flash-Point)

Deviations:

no

GLP compliance:

yes

Type of method:

closed cup

Flash point apparatus:

Pensky-Martens apparatus

Flash point:

> 225 °C

Atm. press.:

101.6 kPa

Remarks on result:

other: Closed Cup Flash Point Temperature : > 225°C. The sample started to boil at approximately 210°C producing grey vapours which extinguished the test flame. The test was terminated at 225°C.

Full test results:

Temperature (°C)	Barometric pressure (kPa)	Ignition Yes (y)/N(n)	Halo/Enlarged test flame?  Yes (y)/N(n)
25 -179	101.6	n	n
180 -225	101.6	n	y
Fresh sample
25 -279	101.6	n	n
180 -225*	101.6	n	y

* due to sample boiling higher test temperature could not be attained and therefore testing was terminated

Interpretation of results:

GHS criteria not met

Conclusions:

Closed Cup Flash Point Temperature : > 225 °C.
The sample started to boil at approximately 210°C producing grey vapours which extinguished the test flame. The test was terminated at 225°C.

Description of key information

Closed Cup Flash Point Temperature : > 225°C. The sample started to boil at approximately 210°C producing grey vapours which extinguished the test flame. The test was terminated at 225°C.

Additional information

Closed Cup Flash Point Temperature : > 225°C. The sample started to boil at approximately 210°C producing grey vapours which extinguished the test flame. The test was terminated at 225°C.
