Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

1998

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Basic data given: comparable to guidelines/standards

Principles of method if other than guideline:

Grewer oven screening and test with higher volume (hot storage test) analogous VDI 2263 sheet 1

Key result

Relative self-ignition temperature:

> 200 °C

Remarks on result:

other:

Remarks:

at atm. press. of ca.1013.0 hPa

The Grewer oven screening showed weak self-heating starting from 270 °C.

When stored at 200 °C, the sample showed weak self-heating and reached a maximum temperature of 208.3 °C 65 minutes after temperature equalisation (which took 2.8 h).

The self-ignition temperature is therefore given as > 200 °C.

Conclusions:

The substance showed weak self-heating in the Grewer oven screening and in a hot storage test (at 200 °C in a 1 L basket). The test item is not a self-heating substance.

Executive summary:

Self-ignition of the test substance was investigated by a Grewer oven screening and a hot storage test. The Grewer oven screening showed weak self-heating at 270 °C. The hot storage test at 200 °C also revealed very weak self-heating of 8 °C.

The self-ignition temperature is given as > 200°C. The test item is not a self-heating substance.

Description of key information

Key study: Self-ignition of the test substance was investigated by a Grewer oven screening and a hot storage test. The self-ignition temperature is given as > 200°C. The test item is not a self-heating substance.
