Results of the preliminary test

Sample No.	Start temperature (°C)	Gradient (°C/min)	Measured flash point (°C)	Atmospheric pressure (kPa)
	-12	1.3	No flash point up to 53°C	101.3
2	50	4.8	No flash point up to 110°C	101.2

Results of the main test

There was no flash point observed up to boiling temperature of the test substance at approximately 110°C. All results of the study are summarised in the following table.

Sample No.	Start temperature (°C)	Gradient (°C/min)	Measured flash point (°C)	Atmospheric pressure (kPa)
1	-12	1.3	No flash point up to 53°C	101.3
2	50	4.8	No flash point up to 110°C	101.2
3	87	0.8	No flash point up to 111°C	101.2
4	87	1.0	No flash point up to 111°C	100.8

The flash point is defined as the lowest measured value out of all performed tests.

There was no flash point up to 110 °C (760 Torr) = 383.2 K (1.013 bar)

Interpretation of results:

GHS criteria not met

Conclusions:

The flash point of the test item is >110 °C.

Executive summary:

The flash point of the test item was determined in a GLP study according to EU test method A.9. The flash point of the test item

is >110 °C. The test item does not have to be classified as a flammable liquid according to Regulation (EC) 1272/2008.

Description of key information

The flash point of the test item is >110 °C, since no flash point could be observed up to 110 °C. A value of 110 °C was entered as the key value.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

110 °C

Additional information

Based on the classification criteria of Regulation (EC) 1272/2008, the test item does not have to be classified as a flammable liquid.
