Key result
Flash point:
229.5 °C
Atm. press.:
1 013 hPa

The following tables show the results of the measurements as temperatures where ignition (+) was detected and where not (-).

Table1:Preliminary test

Test item / g Starting temperature / °C Temperature / °C Ignition + / - Remarks
2 30 100 - -
4 100 200 - Tests was stopped: filling level too high
2 100 200 - Tests was stopped: filling level too high
1 100 255 + -
1 100 237 + -
1 217 233 + -

 

The test item swelled during heating up. At a temperature of 200.0 °C the tests with 2 g and 4 g were stopped due to high filling levels in the apparatus. To ensure a sufficient gas space inside the apparatus which is needed to form a flammable vapour/air mixture the test was continued with 1 g of the test item.

Barometric pressure = 1017.5 hPa

The lowest flash point corrected to 1013 hPa is rounded down with an accuracy of 0.5 °C: 229.5 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item is therefore 229.5 °C at 1013 hPa
Executive summary:

The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), using a Rapid equilibrium closed cup method (ISO3679, 2015).

The test item swelled during heating up. Therefore the main test was performed with 1 g of the test item. The flashpoint of the test item is stated as 229.5 °C (502.65 K) at 1013 hPa.

Description of key information

The substance is NOT classified as a Flammable Liquid according to Regulation (EC) N°1272/2008 (CLP criteria)

and UN Globally Harmonized System (GHS criteria).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
229.5 °C

Additional information

The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), using a Rapid-equilibrium closed cup method (ISO3679). It is considered as a key study. The result is retained as key data for purpose of CSA.
