Relative self-ignition temperature:

>= 320 °C

Remarks on result:

other: pure test substance

Relative self-ignition temperature:

>= 320 °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 320°C was observed leading to a maximum temperature of 370°C.

In the screening test with the kieselgur mixture (1:1) an exothermal effect starting at 320°C was observed. Self-heating led to a temperature of 410°C.

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

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 310°C was observed without further temperature increase (foaming of the test substance)

In the screening test with the kieselgur mixture (1:1) an exothermal effect starting at 300°C was observed. Self-heating led to a temperature of 580 °C.

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
