relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
GLP compliance:
yes (incl. QA statement)
Key result
Relative self-ignition temperature:
> 202 °C
Remarks on result:
at atm. press. of ca.1013.0 hPa

As the pressure is not explicitly stated in the study report, normal pressure is assumed.

No exothermic reaction took place until the melting point of 202°C was reached.

The test item is not auto-flammable.
Executive summary:

The determination of the relative self-ignition temperature of the test item was performed according to the EEC Directive 92/69, Part A, Methods for the determination of physico¬chemical properties, A.16 "Relative self-ignition temperature for solids", EEC Publication No. L383, December 1992.

Using a linear increase in temperature of about 0.5 °C/min, test item showed no relevant exothermic reaction. The test substance has a melting point at 202°C. As the above mentioned guideline only applies to solids, the temperature range between 202°C and 400°C is not relevant for the present test item.

Description of key information

Autoflammability:  not auto-flammable

Key value for chemical safety assessment

Additional information

No exothermic reaction took place until the melting point of 202°C was reached. Since the test substance has a melting point of 202 °C, the temperature range between 202 °C and 400 °C is not relevant for the substance.
