Qualifier:

according to guideline

Guideline:

Relative self-ignition temperature:

>= 340 °C

Remarks on result:

other: pure test substance

Relative self-ignition temperature:

>= 340 °C

Remarks on result:

other: 1:1 mixture of test substance with Kieselguhr

In the screening test according to Grewer with the pure test substance an exothermal effect starting at 340°C was observed, which led to a maximum product temperature of 410°C.

In the screening test with the kieselgur mixture (1:1) the same behaviour was recorded.

Conclusions:

The test item has not to be classified as self-heating substance according to Regulation (EC) No 1272/2008, Annex I, 2.11.4

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
