Key result

Flash point:

190 °C

Atm. press.:

1 013 hPa

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

Table 4.11/1.-Preliminary test

Test item / g	Starting temperature / °C	Temperature / °C	Ignition + / -
2	20	100	-
4	100	191	+
4	100	200	+
4	180	191	+

Table 4.11/2.- Main test, equilibration time: 120 seconds

Test item / g	Temperature / °C	Ignition + / -	Equilibration time / s	Barometric pressure / hPa
4	191.0	-	120	1005.1
4	196.0	-
4	201.0	-
4	206.0	-
4	211.0	-

In the preliminary test (heating ramp of 5 K/min, ignition flame was dipped into the test item every 1 K) ignitions were observed at 191 °C and 200 °C. In the main test (constant oven temperature, for each temperature step a fresh sample is used) no ignition was observed within an equilibration time of 120 seconds up to 211.0 °C.

Subsequently the equilibration time was varied and the ignition flame was dipped into the test item approximately every 10 seconds, Table 4.11/3. Each single test was limited to a maximum duration of 300 seconds or until ignition occurred.

The lowest flash point corrected to 1013 hPa was rounded down with an accuracy of 0.5 °C giving a value of 190.0 °C.

Interpretation of results:

GHS criteria not met

Conclusions:

The flash point of the test item is therefore 190 °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).

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:

190 °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.
