Auto flammability

Link to relevant study record(s)

Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods

Remarks:

According to Directive VDI 2263, part I

Reason / purpose for cross-reference:

reference to same study

Qualifier:

according to guideline

Guideline:

other: Directive VDI 2263, part I

Key result

Relative self-ignition temperature:

>= 310 °C

Remarks on result:

other: pure test substance and 1:1 Kieselguhr mixture

In the screening test according to Grewer with the pure test substance an exothermal effect starting at 310°C was observed, which led to a maximum product temperature of 350°C.

In the screening test with the kieselgur mixture (1:1) an exothermal effect starting at 310°C was observed. Self-heating led to a temperature of 750 °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

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

310 °C
