Key result
Flash point:
135.5 °C
Remarks on result:
other: pressure not specified but assumed to be ambient

Pre-test for safety:

When heating a sample of the test item in an open test tube (10*100 mm) with a gas burner individual bubble was observed at 258 °C and more bubbles were visible at 273 °C. At 294 °C super heating occurred, therefore the gas burner was turned off.

After cooling down the test item was slightly darker (dark brown).

Determination of the flash point:

The results of the determinations are presented in the following table.

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 135.5°C (corresponding to 408.7 K).

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 135.5 °C (corresponding to 408.7 K).
Executive summary:

This study was performed in order to determine the flash point of test item according to EU Method A.9, using a Pensky-Martens apparatus.

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 135.5 °C (corresponding to 408.7 K).

The test item should NOT be classified according to Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS).

Description of key information

The flash point of test item was determined to be 135.5°C. This value is the mean value of two independant determinations.

Test item is not classified as flammable liquid according to Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
135.5 °C

Additional information

A fully reliable experimental study, conducted according to EU A9 guideline is available.

It is considered as a key study, and the result is retained as key data.
