Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study (VDI 2263).
Qualifier:
according to guideline
Guideline:
other: VDI 2263
Relative self-ignition temperature:
270 °C
Remarks on result:
other:
Remarks:
at atm. press. of ca.1013.0 hPa

The pure sample showed self-heating starting from 270 °C (max. temp. ca 380 °C).

It liquefied during the test and flowed partially out of the basket. The remaining amount in the wire basket showed self-ignition.

The mixture with kieselguhr (1:1; prevents the sample from running out of the wire basket) showed self-ignition starting from 290 °C with a temperature rise to above 650 °C due to an oxidation reaction of the test substance with kieselguhr.

Conclusions:
The pure test substance showed self-heating starting from 270 °C. The test item is not a self-heating substance according to UN class 4.2 and GHS/CLP.
Executive summary:

Self-heating of the test substance was analysed by a screening test in the Grewer oven according to VDI 2263, sheet 1. The pure test substance showed self-heating starting from 270 °C. The test item is not a self-heating substance.
